A ROUND ROBIN EXPERIMENT TO PROVIDE PRECISION AND BIAS FOR SEMI MS5: TEST METHOD FOR WAFER BOND STRENGTH MEASUREMENTS USING MICRO-CHEVRON TEST STRUCTURES

December 7, 2009
Author(s)
Richard A. Allen, Winthrop A. Baylies, Paul Langer, Ralph Danzl, Frank W. DelRio, Gavin Horn, Roy Knechtel, Michael Mattes, David T. Read, Sumant Sood, Kevin T. Turner
An international round robin was organized to update SEMI Standard MS5: Test Method for Wafer Bond Strength Measurements using Micro-Chevron Test Structures. Results from the round robin allowed for inclusion of a Precision and Bias statement. The new

Enhanced Water Splitting Performance of Potassium-Adsorbed Titania Nanotube Arrays

December 7, 2009
Author(s)
Christiaan Richter, Cherno Jaye, Eugen Panaitescu, Daniel A. Fischer, Laura H. Lewis, Ronald J. Willey, Latika Menon
It is demonstrated that vertically-aligned titania nanotube planar arrays fabricated by electrochemical anodization using standard potassium-containing electrolytes invariably contain a significant amount of surface-adsorbed potassium ions that enhance the

Improvements in Video-Based Automated System for Iris Recognition (VASIR)

December 7, 2009
Author(s)
Yooyoung Lee, Ross J. Micheals, P J. Phillips
Video-based Automated System for Iris Recognition (VASIR) performs two-eye detection, best quality image selection by adapting human vision and edge density methods, and iris verification. A new method of iris segmentation is implemented and evaluated that

Long-term comparison of caesium fountain primary frequency standards

December 7, 2009
Author(s)
Thomas E. Parker
There are currently nine caesium fountain primary frequency standards regularly reporting calibrations of International Atomic Time to the Bureau International des Poids et Measures (BIPM). An investigation has been carried out using data from the BIPM

Nanotube Length Distributions Measured from Suspension by Electrospray-Differential Mobility Analysis

December 4, 2009
Author(s)
Leonard F. Pease III, De-Hao D. Tsai, Jeffrey A. Fagan, Barry J. Bauer, Rebecca A. Zangmeister, Michael J. Tarlov, Michael R. Zachariah
We present the first systematic characterization of well dispersed, length sorted single-walled carbon nanotubes (SWCNTs) by electrospray-differential mobility analysis (ES-DMA). Although understanding geometric properties of SWCNTs including their length

Fire Safety Risks Associated with Leaks in Hydrogen Systems.

December 3, 2009
Author(s)
Jintao Zhang
Hydrogen presents several unusual fire hazards, including high leak propensity, ease of ignition, and invisible flames. This research concerns experiments, analysis, and computations to identify the hazards of leaks in hydrogen systems that could result in

SER Performance Analysis for Physical Layer Network Coding over AWGN Channel

December 3, 2009
Author(s)
Yi Qian, Kejie Lu, Shengli Fu, Hsiao-Hwa Chen
While original network coding is proposed over data link layer, recent work suggests that it can also be implemented on physical layer. In fact it is more natural for wireless networks because of its omnidirectional transmission. In this paper, we

Synthetic Magnetic Fields for Ultracold Neutral Atoms

December 3, 2009
Author(s)
Yu-Ju Lin, Robert L. Compton, Karina K. Jimenez Garcia, James V. Porto, Ian B. Spielman
Neutral atomic Bose condensates and degenerate Fermi gases have realized important many-body phenomena in their most simple and essential forms, without many of the complexities usually associated with material systems. A rich source of physics in

Thermal Stability of Confined Flip-Chip Laminated w-Functionalized Monolayers

December 3, 2009
Author(s)
Mariona Coll Bau, Curt A. Richter, Christina A. Hacker
We present the results of an IR study of the effect of temperature on the formation of Au-monolayer-Si molecular junctions by using a flip-chip lamination approach. Carboxylic acid-terminated alkanethiols self-assembled on ultrasmooth gold substrate have
