Device-Level Jitter as a Probe of Ultrafast Traps in High-k MOSFETs

April 16, 2016
Author(s)
Dmitry Veksler, Jason Campbell, Kin (Charles) Cheung, J. Zhong, H. Zhu, C. Zhao
A methodology for evaluation of ultra-fast interfacial traps, using jitter measurements as a probe, is developed. This methodology is applied to study the effect of PBTI stress on density of ultra-fast electron traps (with 500ps to 5ns characteristic

Bayesian Calibration of Transferable, Coarse-Grained Force Fields

April 15, 2016
Author(s)
Thomas W. Rosch, Frederick R. Phelan Jr., Paul Patrone
Generating and calibrating forces that are transferable across a range of state-points remains a challenging problem in coarse-grained (CG) molecular dynamics (MD). In this work, we present a Bayesian correction algorithm, inspired by ideas from

Combined Effects of High-Dose Bisphenol A and Oxidizing Agent (KBrO3) on Cellular Microenvironment, Gene Expression, and Chromatin Structure of Ku70-deficient Mouse Embryonic Fibroblasts

April 15, 2016
Author(s)
Erdem Coskun, Pawel Jaruga, Miral M. Dizdar, Natalie Gassman, Samuel Wilson
Background: Exposure to the environmental endocrine disrupting chemical bisphenol A (BPA) has been reported to alter global gene expression, induce epigenetic modifications, and interfere with the complex regulatory networks of cells. In addition to these

Models for the Economics of Resilience

April 15, 2016
Author(s)
Stanley W. Gilbert, Bilal Ayyub
Estimating the economic burden of disasters requires appropriate models that account for key characteristics and decision making needs. Natural disasters in 2011 resulted in $366 billion in direct damages and 29,782 fatalities worldwide. Average annual

Pressure-Resistant Intermediate Valence in the Kondo Insulator SmB 6

April 15, 2016
Author(s)
Nicholas P. Butch, Johnpierre Paglione, Paul Chow, Yuming Xiao, Chris A. Marianetti, Corwin H. Booth, Jason R. Jeffries
Resonant x-ray emission spectroscopy (RXES) was used to determine the pressure dependence of the f-electron occupancy in the Kondo insulator SmB 6. Applied pressure reduces the f-occupancy, but surprisingly, the material maintains a significant divalent

Spin Dynamics and Two-Dimensional Correlations in the FCC Antiferromagnetic Sr 2 YRuO 6

April 15, 2016
Author(s)
Steven M. Disseler, Jeffrey W. Lynn, R. F. Jardim, M. S. Torikachvili, E. Granado
The face-centered cubic lattice lattice of Ru 5+ spins in the double perovskite Sr 2YRuO 6 shows a delicate three dimensional antiferromagnetic (AFM) ground state composed of stacked square AFm layers. Inelastic neutron scattering data taken on this state

Spin-Orbit Coupled Bose-Einstein Condensates

April 15, 2016
Author(s)
Yu-Ju Lin, Karina K. Jimenez Garcia, Ian B. Spielman
Spin-orbit (SO) coupling -- the interaction between a quantum particle's spin and its momentum -- is ubiquitous in nature, from atoms to solids. In condensed matter systems, SO coupling is crucial for the spin-Hall effect and topological insulators; it

Temperature-Dependent Material Modeling for Structural Steels: Formulation and Application

April 15, 2016
Author(s)
Mina S. Seif, William E. Luecke, Lisa Y. Choe, Joseph A. Main, Joseph D. McColskey, Chao Zhang, Jonathan M. Weigand, John L. Gross, Fahim Sadek
This report presents the formulation and application of a newly developed temperature-dependent material model for structural steels. First it presents a model for computing the stress-strain behavior of structural steel for conditions appropriate to fire

Tight real-time synchronization of a microwave clock to an optical clock across a turbulent air path

April 15, 2016
Author(s)
Hugo Bergeron, Laura C. Sinclair, William C. Swann, Craig Nelson, Jean-Daniel Deschenes, Esther Baumann, Fabrizio R. Giorgetta, Ian R. Coddington, Nathan R. Newbury
The ability to distribute the precise time and frequency from an optical clock to remote platforms could enable future precise navigation and sensing systems. Here we demonstrate tight, real-time synchronization of a remote microwave clock to a master

A Fluorinated Metal-Organic Framework for High Methane Storage at Room Temperature

April 14, 2016
Author(s)
Ganggang Chang, Huimin Wen, Bin Li, Wei Zhou, Hailong Wang, Khalid Alfooty, Zongbi Bao, Banglin Chen
A fluorinated metal-organic framework NOTT-108 with single pure-phase has been synthesized for the first time, which has enabled us to examine the effect of the substituted fluorine atoms on the methane storage. The activated NOTT-108a shows a permanent

Dual-comb spectroscopy

April 14, 2016
Author(s)
Ian R. Coddington, Nathan R. Newbury, William C. Swann
Dual-comb spectroscopy is an emerging new spectroscopic tool that exploits the frequency resolution, frequency accuracy, broad bandwidth, and brightness of frequency combs for ultra-high resolution, sensitive broadband spectroscopy. By use of two coherent
