Generalized ellipsometry of artificially designed line width roughness

December 10, 2010
Author(s)
Martin Foldyna, Thomas A. Germer, Brent Bergner, Ronald G. Dixson
We use azimuthally-resolved spectroscopic Mueller matrix ellipsometry to study a periodic silicon line structure with and without artificially-generated line width roughness (LWR). We model the artificially perturbed grating using 1D and 2D rigorous

k-Zero Day Safety: Measuring the Security Risk of Networks Against Unknown Attacks

December 10, 2010
Author(s)
Lingyu Wang, Sushil Jajodia, Anoop Singhal, Steven Noel
The security risk of a network against unknown zero day attacks has been considered as something unmeasurable since software flaws are less predictable than hardware faults and the process of finding such flaws and developing exploits seems to be chaotic

Modeling of Self-Heating Mechanism in the Design of Superconducting Limiters

December 10, 2010
Author(s)
Eduard Rocas, Juan C. Collado Gomez, Jordi Mateu, Nathan D. Orloff, James C. Booth
This work proposes a modeling method to simulate how temperature rise, due to power dissipation, affects the performance of a HTS limiter. The spatial temperature rise distribution across and along a HTS transmission line is determined by heat generation

Low loss superconducting titanium nitride coplanar waveguide resonators

December 9, 2010
Author(s)
Michael Vissers, Jiansong Gao, David S. Wisbey, David P. Pappas, C. C. Tsuei, A. D. Corcoles, Matthias Steffen
Thin films of TiN were sputter-deposited onto Si and sapphire wafers with and without SiN buffer layers. The films were fabricated into RF coplanar waveguide resonators, and internal quality factor measurements were taken at millikelvin temperatures in

Far-ultraviolet signatures of the 3He(n,tp) reaction in noble gas mixtures

December 8, 2010
Author(s)
Patrick Hughes, Alan K. Thompson, Michael Coplan, Robert E. Vest, Charles W. Clark
Previous work showed that the 3He(n,tp) reaction in a cell of 3He at atmospheric pressure generated tens of far-ultraviolet photons per reacted neutron. Here we report amplification of that signal by factors of 1000 and more when noble gases are added to

Mapping Crystal Orientation in High Performance Thienothiophene Copolymer Thin Films

December 8, 2010
Author(s)
Xinran Zhang, Steven D. Hudson, Dean M. DeLongchamp, David J. Gundlach, Martin Heeney, Iain McCulloch
Mapping of crystalline grain orientation for solution-processed semiconducting polymer thin films is key to understanding charge transport in electronic devices based on them and yet challenging. In this work, a high mobility thienothiophene copolymer

Toward Objective Global Privacy Standards

December 8, 2010
Author(s)
Ari M. Schwartz
Technical standards offer a new ability to support the important public policy goal of better protecting privacy. To do so most effectively, we must begin to move from the privacy standards based on subjective and procedural efforts to a series of
