Electrodeposition of Silver in Sub-Micron-Sized Features

February 1, 2002
Author(s)
B C. Baker, Thomas P. Moffat, Daniel Josell, Daniel Wheeler
Successful superfilling of lines and vias will be shown with a commercial, silver-cyanide electrolyte. Hysteretic i-V behavior and chronoamperometric transients on planar electrodes are used to extract parameters that quantify the kinetics of the

Electron Backscatter Diffraction (EBSD) of Single Particles

February 1, 2002
Author(s)
John A. Small
Over the years several different methods have been developed for the quantitative x-ray microanalysis of individual particles Small (1981), Armstrong (1991). Despite the large number of quantitative methods available, the accuracy for the x-ray

Electron-Impact Total Ionization Cross Sections of Hydrocarbon Ions

February 1, 2002
Author(s)
Karl K. Irikura, Yong Sik Kim, M A. Ali
The Binary-Encounter-Bethe (BEB) model for electron-impact total ionization cross sections has been applied to CH 2 +, CH 3 +, CH 4 +, C 2H 2 +, C 2H 4 +, C 2H 6 +, and H 3O +. The cross sections for the hydrocarbon ions are needed for modeling cool

Exchange bias and anisotropy in the Fe/KCoF 3 structure

February 1, 2002
Author(s)
Leszek Malkinski, Nicholas Cramer, Andrew Hutchinson, Robert E. Camley, Zbigniew J. Celinski, Danuta Skrzypek, Ronald B. Goldfarb
A new type of ferromagnet/antiferromagnet structure (fe/KCoF 3) was deposited by molecular beam epitaxy. Unidirectional and uniaxial anisotropies of 5.1 and 3.4 kA/m were measured at 23 K using ferromagnetic resonance. Magnetization measurements at 5 K

Features of Domain Nucleation and Growth in Co/Ru/Co Synthetic Antiferromagnets Deposited on Obliquely Sputtered Ta Underlayers

February 1, 2002
Author(s)
Alexander J. Shapiro, V S. Gornakov, Valerian I. Nikitenko, Robert D. McMichael, William F. Egelhoff Jr., Y W. Tahk, Robert D. Shull, L Gan
Obliquely sputtered Ta underlayers were used to stabilize antiferromagnetically couple Co/Ru/Co/Ta structures with a strong uniaxial anistropy. Magneto-optical indicator film (MOIF) imaging revealed nucleation and growth of domains during remagnetization

First Astronomical Use of Multiplexed Transition Edge Bolometers

We present performance results based on the first astronomical use of mutiplexed superconducting bolometers. The Fabry-Perot Interferometer Bolometer Research Experiment (FIBRE) is a broadband submillimeter spectrometer that achieved first light in June

Foreword for Motohisa Kanda's Special Issue

February 1, 2002
Author(s)
Christopher L. Holloway, Perry F. Wilson
This special issue of the IEEE EMC Transactions is in honor of Dr. Motohisa Kanda who passed away on June 12, 2000. Dr. Kanda, known to most of us simply as "Moto," was an important figure within the EMC community and served as Editor of the IEEE EMC

Guide for the Selection of Communication Equipment for Emergency First Responders

February 1, 2002
Author(s)
Alim A. Fatah, John Barrett, Richard Arcilesi, Patrick Scolla, Charlotte H. Lattin, Susan Fortner
This guide includes information that is intended to assist the emergency first responder community in the selection of communication equipment for different applications. This specific work, Volume II of the Guide for the Selection of Communication

Improved Estimate of the Dissociation Energy of the Beryllium Dimer

February 1, 2002
Author(s)
J A. Harkless
Over the years, electronic structure theorists have frequently returned to the beryllium dimer and its dissociation energy as a problem of enduring popularity. There are two main reasons for this popularity. First, the beryllium dimer is one of the

Intelligent Control For Off-Road Driving

February 1, 2002
Author(s)
Karl Murphy, Marilyn N. Abrams, Stephen B. Balakirsky, Tommy Chang, Tsai Hong Hong, Alberto Lacaze, Steven Legowik
The NIST robot vehicle, a HMMWV with sensors and computer controlled actuators, detects how traversable the terrain is near the vehicle and computes its path and velocity accordingly. During tests the vehicle drives through the back fields of NIST at

International Comparison of Volume Measurement Standards at 50 L at CENAM (Mexico), PTB (Germany), Measurement Canada and NIST (USA)

February 1, 2002
Author(s)
J M. Maldonado, R Arias, H -. Oelze, Vern E. Bean, J F. Houser, C Lachance, Claude Jacques
ntro Nacional de Metrologia (CENAM), Physikalisch-Technische Bundesanstalt (PTB), Measurement Canada (MC), and the National Institute of Standards and Technology (NIST) maintain the national primary standard facilities for the measurement of volume in

Magnetic-Field Imaging of Weakly Bound Levels of the Ground-State Na 2 Dimer

February 1, 2002
Author(s)
T Laue, Eite Tiesinga, C Samuelis, H Knockel, E Tiemann
We measured in a molecular beam experiment the magnetic field dependence of the last bound levels of the X 1Σg + and a 3Σ +u potentials close to the 3s+3s asymptote of Na 2. The field behavior of these levels in an external magnetic field differs for even

Mass Absorption Coefficient of Tungsten for 1600-2100 eV

February 1, 2002
Author(s)
Zachary H. Levine, S Grantham, I McNulty
The transmission of soft x-rays with photon energies from 1606 eV to 2106 eV was measured for tungsten using thin film samples and a synchrotron source. This region includes the M IV and M V edges. The two tungsten films had thicknesses of 107.7 10 nm and

Measuring Droplet Arrival Times Using Phase Doppler Interferometry

February 1, 2002
Author(s)
J F. Widmann, Cary Presser
The difficulty of accurately measuring droplet arrival time statistics is demonstrated using phase Doppler interferometry (PDI) measurements obtained in water sprays produced by pressure-swirl atomizers. It is shown that Doppler burst splitting, in which

MEMS Device Platforms as Research Tools for Developing Improved Sensing Films

February 1, 2002

C J. Taylor, Richard E. Cavicchi, Stephen Semancik
Gas sensing characteristics of metal oxide films are dependent on the preparation method used in their fabrication. To optimize sensing film performance, one must understand how processing parameters influence composition andmicrostructure, and then

Model Checkers in Software Testing

February 1, 2002
Author(s)
Paul E. Black, P E. Ammann, W Ding
The primary focus of formal methods is static analysis of specifications and code, but there is also a long tradition of exploiting formal methods for testing. This paper continues this model by exploring the role of model checkers in software testing

Molecular Basis of Lubrication

February 1, 2002
Author(s)
