Intercomparisions of Reflectance Measurements

October 16, 2008
Author(s)
P Y. Barnes, B. Carol Johnson, James J. Butler, C J. Bruegge, S F. Biggar, P R. Spyak, M M. Pavlov, E A. Early
A comparison of spectral diffuse reflectance between different national standards laboratories is being planned under the direction of the Comit* Consultatif de Photom*trie et Radiom*trie (CCPR). A similar comparison of bi-directional reflectance

Interconnect Failure Due to Cyclic Loading

October 16, 2008
Author(s)
R R. Keller, Reiner Monig, Cynthia A. Volkert, E Arzt, R Schwaiger, O Kraft
The damage generated by AC currents at 100 Hz in interconnects has been studied andcompared with mechanical fatigue damage in thin films. The nature of the damage under the twoloading conditions is qualitatively similar, supporting the idea that the AC

Interfacial Free Energies and the Creep of Multilayer Thin Films

October 16, 2008
Author(s)
Daniel Josell, W Carter
Experiments utilizing the creep properties of multilayer thin films to determine underlying free energies are presented with essential theory. A new technique utilizing tubular multilayer foils is then described.

Internal Friction Tensor in Langasite (LA 3 Ga 5 SiO 14 )

October 16, 2008
Author(s)
H M. Ledbetter, Sudook A. Kim
Using acoustic spectroscopy, we measured the complete elastic-constant and internal-friction tensor C y = C y (1+Q -1 y) of langasite, a trigonal-symmetry piezoelectric. To understand the internal friction, we need a mechanism that explains, or is

International Comparison CCQM-K41: Hydrogen Sulfide in Nitrogen

October 16, 2008
Author(s)
Franklin R. Guenther, Walter R. Miller Jr.
This key comparison was intended to compare the capabilities for the preparation and value assignment of gas standards for hydrogen sulfide in nitrogen, maintained at the participating national metrology institutes. The range of the nominal amount-of

Investigation of N 2 Plasma Effects on the Depth Profile of Hydrogen Silsesquioxane Thin Films Using High Resolution Specular X-Ray Reflectivity

October 16, 2008
Author(s)
Hae-Jeong Lee, Eric K. Lin, J K. Lan, Y L. Cheng, H C. Liou, Wen-Li Wu, Y L. Wang, M S. Feng, C G. Chao
Non-destructive, specular X-ray reflectivity (SXR) measurements were used to investigate N2 plasma effects on the density depth profile of hydrogen silsesquioxane (HSQ) thin films. The SXR data indicate that the density profile of an HSQ film without

Issues and Trends in Legal Metrology (from a U.S. Perspective)

October 16, 2008
Author(s)
Charles D. Ehrlich, H V. Oppermann
Several current aspects of legal metrology are likely to change significantly over the next 10 years to 20 years. Exponential increase in the use of technology in the marketplace requires legal metrology officials to become increasingly knowledgeable in a

IUPAC/NIST Solubility Database

October 16, 2008
Author(s)
G R. Dalton, Angela Y. Lee, S L. Young
A database containing solubilities originally published in the International Union for Pure and Applied Chemistry (IUPAC)-NIST Solubility Data Series has been made available online. The data were originally published in eleven volumes of the Solubility

Key Concepts in Evaluating Outcomes of ATP Funding of Advanced Technologies

October 16, 2008
Author(s)
Andrew J. Wang
The Economic Assessment Office (EAO) of the Advanced Technology Program (ATP) commissions economic studies by outside research organizations. A recent study by the Research Triangle Institute (RTI) outlines a framework for evaluating ATP funding of medical

Kinetic Simulations of Crystal Growth With (Nearly) Realistic Physics

October 16, 2008
Author(s)
J L. Blue
Many kinetic Monte Carlo simulations of expitaxial crystal growth have been done using a simple cubic crystal structure and over-simplified physics. We discuss how to improve these simulations in a general-purpose computer program that can handle correct

Kinetics of Polymer Phase Separation

October 16, 2008
Author(s)
Charles C. Han
Kinetics of polymer phase separation has been briefly reviewed. This is a section on this subject for Encyclopedia of Materials: Science and Technology. This section includes summary of sinodal decomposition, critical temperature shift under shear flow

Knowledge and Uniformity

October 16, 2008
Author(s)
H V. Oppermann
Two primary objectives of weights and measures enforcement are to promote fair competition among companies and to ensure accurate measurement for consumers. To achieve these objectives, it is necessary to have knowledgeable weights and measures officials
