Random Telegraph Noise in Highly Scaled nMOSFETs

April 26, 2009
Author(s)
Jason P. Campbell, Jin Qin, Kin P. Cheung, Liangchun (. Yu, John S. Suehle, A Oates, Kuang Sheng
Recently 1/f and random telegraph noise (RTN) studies have been used to infer information about bulk dielectric defects' spatial and energetic distributions. These analyses rely on a noise framework which involves charge exchange between the inversion

Expanding Environmental Information Management: Meeting Future Requirements

April 25, 2009
Author(s)
John V. Messina, Eric D. Simmon
The environmental impact of product manufacturing, use, and disposal has become a worldwide concern. Laws and regulations designed to protect human health and the environment are being established throughout the global community. In addition to regulatory

Equilibrium Polymerization Models of Reentrant Self-Assembly

April 24, 2009
Author(s)
Jacek Dudowicz, Jack F. Douglas, Karl Freed
As is well known, liquid-liquid phase separation can occur either upon heating or cooling, corresponding to lower and upper critical solution phase boundaries, respectively. Likewise, self-assembly transitions from a monomeric state to an organized

Evaluating the locality of intrinsic precession damping in transition metals

April 24, 2009
Author(s)
Keith Gilmore, Mark D. Stiles
The Landau-Lifshitz-Gilbert damping parameter is typically assumed to be a local quantity, independent of the magnetic configuration. To test the validity of this assumption we calculate the precession damping rate of small amplitude non-uniform mode

From Network Microeconomics to Network Infrastructure Emergence

April 24, 2009
Author(s)
Vladimir V. Marbukh
This paper suggests that evolutionary models of network infrastructure in market economy can be derived from the underlying selfish behavior of users and providers of network services in the same way as non-equilibrium thermodynamics is derived from the

Optimized Dynamical Decoupling in a Model Quantum Memory

April 23, 2009
Author(s)
Michael J. Biercuk, Hermann Uys, Aaron Vandevender, N. Shiga, Wayne M. Itano, David J. Wineland, John J. Bollinger
We demonstrate the efficacy of optimized dynamical decoupling pulse sequences in suppressing phase errors in a model quantum memory. Our experimental system consists of a crystalline array of trapped 9Be + ions in which we drive a qubit transition at $\sim

EtherNet/IP Interoperability Recommendations

April 22, 2009
Author(s)
James D. Gilsinn, Kevin Knake
The EtherNet/IP interoperability recommendations are a result of work generated by the ongoing series of EtherNet/IP Implementors Workshops. The recommendations were created to promote EtherNet/IP device interoperability through product functionality

Itinerant spin excitations near the hidden order transition in URu2Si2

April 22, 2009
Author(s)
J. A. Janik, H. D. Zhou, Y.-J. Jo, L. Balicas, G. J. MacDougall, G. M. Luke, J. D. Garrett, K. J. McClellan, E. D. Bauer, J. L. Sarrao, Yiming Qiu, John R. Copley, Z. Yamani, W. J. Buyers, C. R. Wiebe
By means of neutron scattering we show that the high-temperature precursor to the hidden order state of the heavy fermion superconductor URu 2Si 2 exhibits heavily damped incommensurate paramagnons whose strong energy dispersion is very similar to that of

Robust, conductive ordered mesoporous films based on carbon-silica composites

April 22, 2009
Author(s)
Lingyan Song, Dan Feng, Casey G. Campbell, Aaron M. Forster, Dongyuan Zhao, Bryan D. Vogt
Mesoporous carbon-based sensors have been demonstrated to have enhanced electrochemical response as a result of their large interfacial area. To date, mesoporous carbon powders held together by a polymeric binder have been typically utilized. However for

New International Formulation for the Viscosity of H2O

April 21, 2009
Author(s)
Marcia L. Huber, Richard A. Perkins, Arno R. Laesecke, Daniel G. Friend, Jan V. Sengers, Marc J. Assael, Ifigenia N. Metaxa, Eckhard Vogel, Radim Mares, Kiyoshi Miyagawa
The International Association for the Properties of Water and Steam (IAPWS) encouraged an extensive research effort to update the IAPS Formulation 1985 for the Viscosity of Ordinary Water Substance, leading to the adoption of a Release on the IAPWS

A microfabricated photonic magnetometer

April 20, 2009
Author(s)
Jan Preusser, Svenja A. Knappe, John Kitching, Vladislav Gerginov
We present initial measurements of an atomic magnetometer in which the microfabricated sensor head is coupled to the control system by optical fibers. Since there are no electrical connections, the sensor head is largely non-magnetic and degradation of the

Frequency comb spectroscopy with coherent optical sampling

April 20, 2009
Author(s)
Ian R. Coddington, Nathan R. Newbury, William C. Swann
A stabilized frequency comb provides a broadband array of highly resolved comb lines. Using a multiheterodyne technique, we measure the amplitude and phase of every comb line, allowing for massively parallel, high-resolution spectroscopy.

Markov Chain Analysis for Large-Scale Grid Systems

April 20, 2009
Author(s)
Christopher E. Dabrowski, Fern Y. Hunt
In large-scale grid systems with decentralized control, the interactions of many service providers and consumers will likely lead to emergent global system behaviours that result in unpredictable, often detrimental outcomes. This possibility argues for

A Ferroelectric Oxide Directly on Silicon

April 17, 2009
Author(s)
Joseph C. Woicik, Maitri P. Warusawithana, Cheng Cen, Charles R. Sleasman, Yulan Li, Jeffery Kluga, Lena F. Kourkoutis, Hao Li, Li-Peng Wang, Michael Bedzyk, David A. Muller, Long-Qing Chen, Jeremy Levy, Darrell G. Schlom
Silicon and silicon dioxide form what is arguably the most important technological interface. With the end of Moore s-law scaling for silicon fast approaching, alternatives to silicon dioxide are being pursued that may enable new device architectures and
