＠ Effect of discharge microwave frequency on electron temperature of electron cyclotron resonance plasma:

Y. Kawai, T. Suzuki, T. Saburi, and Y. Fujii; pp. 1666-1667

The characteristics of argon electron cyclotron resonance plasma discharged by 7.0, 8.0, and 9.4 GHz microwaves were investigated. Experiments were conducted in a fixed magnetic field. It was found that the electron temperatures Te exhibited a trend of Te7.0

＠ An add-on secondary electron energy spectrometer for scanning electron microscopes:

A. Khursheed and N. Karuppiah; pp. 1708-1714

This article presents an add-on secondary electron energy spectrometer for scanning electron microscopes (SEMs). The add-on unit fits on to the specimen stage of a conventional SEM, and the SEM is operated as normal. As an objective lens, the add-on unit improves the SEMs spatial resolution by around a factor of 4 at a primary beam energy of 1 keV. The add-on unit functions as a multichannel open-loop voltage contrast spectrometer by employing a bandpass deflector/filter unit whose pass energy is ramped with time. The unit is designed to deflect the secondary electrons while leaving the primary beam unaffected. Initial experimental results show that significant voltage and material contrast can be obtained. In a data acquisition time of 0.32 s, a minimum detectable voltage difference of around 54 mV was obtained. Regions of copper and brass that were indistinguishable via the normal secondary electron image, were distinguished with a signal to noise ratio of around 12 by using the add-on spectrometer.

＠ Surface potential measurements of electron-irradiated insulators using backscattered and secondary electron spectra from an electrostatic toroidal spectrometer adapted for scanning electron microscope applications:

O. Jbara, M. Belhaj, S. Odof, K. Msellak, E. I. Rau and M. V. Andrianov; pp. 1788-1795

A technique for the accurate determination of the surface potential US and its evolution during irradiation, is proposed. The technique is based on detecting both backscattered (BSE) and secondary electrons (SE) in a scanning electron microscope (SEM). The (BSE + SE) spectra are measured using a compact, highly sensitive electrostatic toroidal spectrometer (ETS), specially adapted for SEM applications. The use of an ETS analyzer set in a SEM for deducing the surface potential from (SE + BSE) spectra of electron irradiated insulators is introduced here. The surface potential is determined, either from the measured maximum energy of the secondary electron peak, or from its beginning. Various dielectric materials such as MgO, Al2O3, Y2O3, mica (potassium silicate aluminum), and Teflon were studied by this technique. Experimental investigations of the beam energy and current effects on the surface potential of bare insulators are reported. The change, due to this surface potential, in some physical quantities such as the amount of BSEs and the most probable energy of their spectral distribution is also studied. The results concerning coated and grounded insulators highlight the influence of the internal electric field on the BSEs energy distribution. An account of the various benefits of using the toroidal spectrometer in the surface potential measurement is also given.

#12 [paper] PRB 63(7) 15 Feb 2001

＠ Optical functions and electronic structure of CuInSe2, CuGaSe2, CuInS2, and CuGaS2:

M. I. Alonso, K. Wakita, J. Pascual, M. Garriga, and N. Yamamoto; # 075203

We report on the complex dielectric tensor components of four chalcopyrite semiconductors in an optical energy range (1.4-5.2 eV, from 0.9 eV for CuInSe2) determined at room temperature by spectroscopic ellipsometry. Our results were obtained on single crystals of CuInSe2, CuGaSe2, CuInS2, and CuGaS2. Values of refractive indices n, extinction coefficients k, and normal-incidence reflectivity R in the two different polarizations are given and compared with earlier data where available. We analyze in detail the structures of the dielectric function observed in the studied energy region. Critical-point parameters of electronic transitions are obtained from a fitting of numerically calculated second-derivative spectra d^2e(w)/dw^2. Experimental energies and polarizations are discussed on the basis of published band-structure calculations.

＠ Intrinsic n-type versus p-type doping asymmetry and the defect physics of ZnO:

S. B. Zhang, S.-H. Wei, and Alex Zunger; #075205

ZnO typifies a class of materials that can be doped via native defects in only one way: either n type or p type. We explain this asymmetry in ZnO via a study of its intrinsic defect physics, including Zn_O, Zn_i, V_O, O_i, and V_Zn and n-type impurity dopants, Al and F. We find that Zn_O is n type at Zn-rich conditions. This is because (i) the Zn interstitial, Zn_i, is a shallow donor, supplying electrons; (ii) its formation enthalpy is low for both Zn-rich and O-rich conditions, so this defect is abundant; and (iii) the native defects that could compensate the n-type doping effect of Zn_i (interstitial O, Oi, and Zn vacancy, V_Zn), have high formation enthalpies for Zn-rich conditions, so these "electron killers" are not abundant. We find that Zn_O cannot be doped p type via native defects (O_i, V_Zn) despite the fact that they are shallow (i.e., supplying holes at room temperature). This is because at both Zn-rich and O-rich conditions, the defects that could compensate p-type doping (V_O, Zn_i, Zn_O) have low formation enthalpies so these "hole killers" form readily. Furthermore, we identify electron-hole radiative recombination at the V_O center as the source of the green luminescence. In contrast, a large structural relaxation of the same center upon double hole capture leads to slow electron-hole recombination (either radiative or nonradiative) responsible for the slow decay of photoconductivity.

＠ Resonant photoemission of TiN films:

G. G. Fuentes, P. Prieto, C. Morant, C. Quiros, R. Nunez, L. Soriano, E. Elizalde, and J. M. Sanz; #075403

The bonding and electronic structure of TiN thin films grown by sputtering have been characterized by means of resonant photoemission spectroscopy using synchrotron radiation. Specifically we found a complex resonance profile that exhibits a maximum at 45 eV followed by a second structure at 50 eV. The intensity enhancement observed at 45 and 50 eV is consistent with the resonant photoemission of the Ti 3d states involved in the valence band of TiN and the multiplet configuration of the [Ti 3p^5 3d^2]* excited states. The autoionizing character of the [Ti 3p^5 3d^2]* states could also be confirmed by observation of the corresponding autoionization emission. The resonance is used to determine the Ti 3d contribution to the valence band. The results are in good agreement with calculated Ti 3d partial density of states.

#13 [paper] PRL 63(8) 15 Feb 2001

＠ Si(313)12x1: Another metallic stable surface of silicon having a complex reconstructed layer:

Zheng Gai, R. G. Zhao, T. Sakurai, and W. S. Yang; #085301

By means of scanning tunneling microscopy, the Si(313)12x1 surface has been found to be, after Si(111)7x7, another stable elemental semiconductor surface with a metallic nature. On the basis of the details revealed by the high resolution STM images, an atomically rough model consisting of trenches and a variety of building entities has been proposed for the surface structure for further investigation. The common features of major stable silicon surfaces as well as the similarities and differences between these surfaces and their germanium counterparts are discussed in the context of the driving forces behind the reconstruction of elemental semiconductor surfaces.

＠ Ion bombardment of reconstructed metal surfaces: From two-dimensional dislocation dipoles to vacancy pits:

O. Rodriguez de la Fuente, M. A. Gonzarez, and J. M. Rojo; #085420

By means of scanning tunnel microscopy the surface morphology of reconstructed Au(001) surfaces has been studied after bombardment with 600 eV Ar ions as a function of dose, in the range of 10^13 to 10^16 ions/cm2, and the experimental results analyzed in the light of molecular dynamics simulations using a glue potential. At low dose (5x10^13 ions/cm^2) new defects, different from the commonly observed vacancy islands are reported. They appear as depressions 0.06 nm deep, with a characteristic width of 1.44 nm. Bombardment with similar doses of Pt(001) show the same general behavior. Molecular dynamics simulations with a realistic glue potential that reproduces the hexagonal-like Au(001) reconstruction, confirm that these depressions are in fact two-dimensional /3 dislocation dipoles originated by the relaxation of vacancy rows on the ridges of the topmost reconstructed layer. These two-dimensional dipoles are seen to dissociate into individual two-dimensional dislocations that display the characteristics of ordinary bulk dislocations, e.g. glide or climb. At higher doses (3x10^14 ions/cm^2), but well below a nominal removal of 1 monolayer, vacancy islands, one atomic spacing high, are seen to nucleate on these depressions. With increasing ion damage these vacancy islands become the dominant feature. For doses of about 10^15 ions/cm^2, other defects related to the reconstruction, such as perpendicular reconstruction domains and unreconstructed patches of (001) square symmetry, become visible.

＠ Vaporization of heated materials into discharge plasmas:

Michael Keidar, Jing Fan, Iain D. Boyd and Isak I. Beilis; pp.3095-3098

The vaporization of condensed materials in contact with high-current discharge plasmas is considered. A kinetic numerical method named direct simulation Monte Carlo (DSMC) and analytical kinetic approaches based on the bimodal distribution function approximation are employed. The solution of the kinetic layer problem depends upon the velocity at the outer boundary of the kinetic layer which varies from very small, corresponding to the high-density plasma near the evaporated surface, up to the sound speed, corresponding to evaporation into vacuum. The heavy particles density and temperature at the kinetic and hydrodynamic layer interface were obtained by the analytical method while DSMC calculation makes it possible to obtain the evolution of the particle distribution function within the kinetic layer and the layer thickness.

＠ In situ determination of absolute number densities of nitrogen molecule triplet states in an rf-plasma sheath:

B. Krames, Th. Glenewinkel-Meyer and J. Meichsner; pp.3115-3120

A laser induced fluorescence technique (LIF) in combination with optical emission spectroscopy (OES) and Rayleigh scattering (RS) was applied to investigate absolute number densities of the population of the three nitrogen triplet states C^3Πu, B^3Πg, and the metastable A^3Σ u+ in an asymmetric low pressure rf discharge. Primary targets of this investigation were the three lowest vibrational levels (v = 0,1,2) of each triplet state and additionally v = 8 of A^3Σu+ which can be populated very efficiently in the plasma sheath. Calibration of LIF intensities to absolute densities of A^3Σu+ and B^3Πg has been realized by comparison with the signal of the RS experiment done in pure nitrogen gas. Calibration of C^3Πu which we could not detect by LIF but rather only by OES was achieved after comparing OES and LIF signals of the B^3Πg state. Excitation energies of the analyzed states range from 6 up to 11.5 eV and the measured number densities differ by about seven orders of magnitude from as much as 1012 cm?3 down to almost 105 cm?3. In addition to the interpretation of the results this article describes the used calibration methods which are partly based on a suggestion made by P. Bogen (Proceedings of the XVI International Conference on Phenomena in Ionized Gases, Invited Papers, edited by W. Botticher, H. Wenk, and E. Schultz-Gulde, Dusseldorf, 1983, pp. 164-173).

＠ Chemical modification of sputtered amorphous-carbon surfaces:

Pieter B. Leezenberg, William H. Johnston, and George W. Tyndall; pp.3498-3507

Methods to chemically passivate the surfaces of amorphous-carbon films (a-C) produced by dc magnetron sputtering were studied. The chemical composition of carbon surfaces produced via sputtering are dependent upon the environment to which the carbon is exposed immediately following deposition. When the sputtered film is vented to ambient conditions, free radicals produced at the surface during the deposition process are quenched by reaction with oxygen and/or water to form an oxidized, hydrophilic surface. If the sputtered carbon film is, however, exposed to a reactive gas prior to venting to ambient, the chemical nature of the resulting surface can be modified substantially. Specifically, a less highly oxidized and much more hydrophobic carbon surface is produced when the surface free radicals are quenched via either an addition reaction (demonstrated with a fluorinated olefin) or a hydrogen abstraction reaction (demonstrated with two alkyl amines). Chemical modification of amorphous-carbon films can also be accomplished by performing the sputtering in a reactive plasma formed from mixtures of argon with molecular hydrogen, amines, and perfluorocarbons. The elemental composition of these films, and the relative reactivity of the surfaces formed, were investigated via x-ray photoelectron spectroscopy and contact-angle goniometry, respectively. In the case of sputtering with a mixture of argon and hydrogen, increasing the hydrogen flow results in an increase in the amount of hydrogen incorporated into the carbon film and a decrease in the surface free energy. Sputtering in diethylamine produces an amorphous-carbon film into which nitrogen is incorporated. The free energies of the a-C:N surfaces produced in this process are similar to those of the a-C:H films. Sputtering in a fluorocarbon vapor results in the incorporation of fluorine into the film structure and the formation of very low free-energy surfaces. Increasing the concentration of the fluorocarbon in the sputtering plasma increases the amount of F incorporated into the film. At the highest fluorocarbon flow rates employed, a-C films were produced with stoichiometries and surface free energies comparable to those of bulk Teflon.

• CvsGraph 1.1.0

    CvsGraph is a utility for generation of graphical representation of  revisions and branches from a CVS/RCS repository.    Changes: This is a major rewrite of a lot of code.  CvsGraph reads the  repository file directly, which enables the proper evaluation of the tree  structure in the repository when revision numbers are not in order.  Branches are compacted horizontally so that a tree with many branches  doesn't take too much space. Branches with no revisions are shown.  Branches and revisions which are not in sequence or do not start at 1.1 are  properly plotted.  Minor configure updates, implementation of imagemaps, an  ability to generate HTML that allows linking in the form of imagemaps,  changes to some configuration parameters, and an ability to add custom  expansion string from the command-line using -[0-9].  The executable has  become significantly larger because of table optimization in flex. You can  disable the optimization in configure with '--disable-speed'. This will  slow the execution, but reduce the size.

＠ A thermal Re-emission Model:

Amit Kr. Chattopadhyay; #0103019

Starting from a continuum description, we study the non-equilibrium roughening of a thermal re-emission model for one and two spatial dimensions. Using standard analytical techniques, we map our problem to a generalized version of an earlier non-local KPZ (Kardar-Parisi-Zhang) model. In 2+1 dimensions, the values of the roughness and the dynamic exponents calculated from our theory go like $ \alpha \approx z \approx 1 $ and in 1+1 dimensions, the exponents resemble the KPZ values for low vapor pressure, supporting experimental results. Interestingly, Galilean invariance is maintained althrough.

SISAL

SISAL is an efficient functional programming language for numerical computation on both serial and parallel computers. It has advantages of safety and clarity over conventional programming languages, and it parallelizes without programmer intervention on certain machines. (Unfortunately, not Linux for now!)

Selected Computing Sciences Technical Reports (Lucent Tech.)

#54 が "Nroff/Troff User's Manual"。

fping - a program to ping hosts in parallel

fping is a ping(1) like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up.

ippl - IP Protocols Logger

ippl is a daemon which logs IP packets sent to a computer. It runs in the background, and displays information about the incoming packets.

• extractdiff 0.0.0

    You can use extractdiff to extract or exclude patches from patch files  according to a shell  wildcard pattern.  

  これではナンノコッチャだが、 こういういもの らしい。diff -r したパッチに使うのね。
• Nessus 1.0.7a

    Changes: This release fixes a bug in the scanners timeout.  

• vsftpd 0.0.14

    vsftpd is an FTP server written from the ground up to be free of security  holes, whilst providing safeguards so the impact is low if it isn't. It is  also very small and fast.    Changes: Fixes for nasty bugs whereby the data connection timeout went off  incorrectly, per-user chroot(), a banned anonymous email address list, PASV  range restriction, minor performance enhancements, a vsftpd.conf.5 man  page, and non-PAM local authentication.  

  ふーむ。

#4 [linux] ReiserFS and NFS

from "Journaling with ReiserFS" on LJ Feb 2001

ReiserFS has problems supporting NFS because 64 bits of information are required to find an object in the tree, and NFS expects to find an inode with just the inode number (32-bits long). The good news is the NFS file handle has enough room to store the extra information ReiserFS needs in order to find the file again later, and other kernel developers have written APIs to give the file system control over some of the file handle. By the time this article is out, there should be public patches to add proper NFS support to ReiserFS.

ということらしい。

#4 [linux] mailcrypt

なぜか一度 mc-sign をした後でないと mc-sign-region できなかったので、 /usr/share/emacs/site-lisp/mailcrypt/mailcrypt.el を覗きつつ

  (load-library "mailcrypt")  (mc-setversion "2.6")  (autoload 'mc-sign-region "mc-toplev" nil t)  

としたらできるようになった。 とはいえどこにも 公開鍵 登録してないので、sign することなど実生活ではほとんどないのだが(苦笑)

• apt-sources 2.0

    Apt-sources simplifies the task of finding the nearest APT servers. The  server list can be either downloaded and parsed from Debian.org or read in  from a local file via a command-line argument. The scoring of the servers  is done using embedded Netselect source code for distance (hops) and  latency. The user also has the option of testing the servers using embedded  BING source code for bandwidth scoring. Other command-line arguments  include saving top placing servers to a file for future scoring and  distribution selection (stable, unstable, and testing).    Changes: Apt-Sources v2.0 has been totally rewritten. It has rid itself of  Netselect and Bing source code and all other external source code. It now  benchmarks lists of Debian mirrors via FTP and generates a sources.list of  the best servers.  

  ふむむ。
• Gnome Flow 0.9.12

    Gnome Flow is a program written to calculate and visualize simple  steady-state fluid flows. It uses the relaxation method, and can calculate  flows past symmetric objects. Steady-state means that it calculates the  flow at a given time, and that the physical parameters are constant in  time.    Changes: Object data can be loaded from graphic files of many formats.  Timer driven pressure calculation was added. Online help was updated.  

• latex2slides 0.1

    Latex2slides is a simple graphical program that  produces a set of  HTML/jpeg slides from a TeX or  LaTeX source.  

• NuLab 0.1

    NuLab is a numeric (not symbolic as Mathematica/Maple, but numercial as  MatLab) math program.    License: Free for non-commercial use  

• SciGraphica 0.6.3

    ciGraphica is a scientific application for data analysis and technical  graphics. It pretends to be a clone of the popular commercial application  "Microcal Origin", supplying plotting features for 2D, 3D, and polar  charts. It features opening several worksheets and plots to work with at  the same time, fully-configurable plots using a control panel dialog, a  completely WYSIWYG look and feel, and publication-quality PostScript  output.    Changes: This release adds improved Postscript output, a preferences  dialog, the first version of a Bonobo interface, emergency save in case of  a crash, and dozens of bugfixes.
