Spectroscopic Ellipsometry of Ta 2 0 5 On Si, in Ultrathin SiO 2 and High-K Materials for ULSI Gate Dielectrics, edited by H. R. Huff, C. A. Richter, M. L. Green, G. Lucovsky, and T. Hattori

September 1, 1999
Author(s)
Curt A. Richter, Nhan Van Nguyen, G A. Alers
In this paper, we present the results of spectroscopic ellipsometry (SE) studies of Ta 20 5 films on Si. Based on these results, we have experimentally determined an effective method for analyzing SE measurements of Ta 20 5. A set of CVD-grown Ta 20 5

Standards-Based Software Testing in a Net-Centric World

September 1, 1999
Author(s)
KC Morris, David Flater
Automation for product development and manufacturing is changing to take advantage of the recent expansion of the Internet and the computing technologies supporting it. These processes are becoming more software independent, and the software used is

Structured Markup on the Web: A Tale of Two Sites

September 1, 1999
Author(s)
Joshua Lubell
Business and organizations are increasingly finding that HTML (Hyper-Text Markup Language)offers no help whatsoever in managing the information on their web sites. SGML (Standard Generalized Markup Language) provides the flexibility and reuse lacking in

Switching Mechanism of Single Domain Particles in a Two-Dimensional Array

September 1, 1999
Author(s)
Martha Pardavi-Horvath, G Vertesy, B Keszei, Z Vertesy, Robert D. McMichael
The mechanism of switching of uniaxial, single domain, single crystalline epitaxial garnet particles on a 2D square array was investigated. The anisotropy field of the sample is 2 kOe, while the gaussian switching field distribution is 280 85 Oe. The

The Representation of Function in Computer-Based Design

September 1, 1999
Author(s)
Simon Sykman, Ram D. Sriram, J Racz
This paper proposes a standardized representation of function for use by the research community, industry, and eventually commercial software vendors. This includes schemata (information models) for representation of function and associated flows, as well

The Use of XML to Describe Function and Taxonomies in Computer-based Design

September 1, 1999
Author(s)
Simon Sykman, Ram D. Sriram, Jocelyn Senfaute
This paper presents a mapping of a standardized representation of a function, consisting of schemata for functions and associated flows. Along with taxonomies of generic functions and flows, into the Extensible Markup Language (XML). A language similar in

Thermophysical Properties of Natural Refrigerants

September 1, 1999
Author(s)
Joe W. Magee
Natural refrigerants are candidates to replace halogenated hydrocarbons as working fluids in refrigeration systems. This class of substances is loosely defined to include carbon dioxide, ammonia, water, air, nitrogen, hydrogen, helium, light hydrocarbons

Three-Body Wear of a Hand-Consolidated Silver Alternative to Amalgam

September 1, 1999
Author(s)
Hockin D. Xu, F Eichmiller, Anthony A. Giuseppetti, L K. Ives, Edward E. Parry, Gary E. Schumacher
Recent studies have investigated a mercury-free silver alternative to amalgam, but the silver powders required a relatively high compaction pressure to consolidate. The aim of the present study was to consolidate a precipitated silver powder into a

Transient Target Patterns in Phase Separating Filled Polymer Blends

September 1, 1999
Author(s)
Alamgir Karim, Jack F. Douglas, G Nisato, D W. Liu, Eric J. Amis
Recent simulations have indicated that the presence of filler particles in a phase separating blend can induce the development of composition waves having the symmetry of the filler particles. We investigate these predictions through atomic force

Transmission Near-Field Scanning Microscope for Infrared Chemical Imaging

September 1, 1999
Author(s)
B Dragnea, J Preusser, W Schade, S R. Leone, W D. Hinsberg
We report transmission infrared near-field scanning microscopy (IR-NSOM) imaging of chemically amplified photoresist polymers patterned by ultraviolet exposure. Chemical specificity was attained using infrared wavelengths tuned to the 3 m OH stretch

Transport Properties and Durability of Concrete: Literature Review and Research Plan

September 1, 1999
Author(s)
Dale P. Bentz, J R. Clifton, Chiara F. Ferraris, Edward J. Garboczi, J M. Torrents
The increased emphasis on life cycle cost analysis for building projects requires that new attention be focused on the service life and durability of concrete structures. While concrete is typically specified based on compressive strength and slump, it is

Vortices in a Bose-Einstein Condensate

September 1, 1999
Author(s)
M R. Matthews, B P. Anderson, P C. Haljan, C E. Wieman, Eric A. Cornell
We have created vortices in two-component Bose-einstein condensates. The vortex state was created through a coherent process involving the spatial and temporal control of interconversion between the two components. Using an interference technique, we map
