Quasiparticle scattering from topological crystalline insulator SnTe (001) surface states

June 27, 2014
Author(s)
Duming Zhang, Hongwoo H. Baek, Jeonghoon Ha, Tong Zhang, Jonathan E. Wyrick, Albert Davydov, Young Kuk, Joseph A. Stroscio
Recently, the topological classification of electronic states has been extended to a new class of matter known as topological crystalline insulators. Similar to topological insulators, topological crystalline insulators also have spin-momentum locked

A classical channel model for gravitational decoherence

June 26, 2014
Author(s)
Jacob M. Taylor, Dvir Kafri, G J. Milburn
We show that, by treating the gravitational interaction between two mechanical resonators as a classical measurement channel, a gravitational decoherence model results that is equivalent to a model first proposed by Diosi. The resulting decoherence model

Interface Engineering to Control Magnetic Field Effects of Organic-Based Devices by Using a Molecular Self-Assembled Monolayer

June 26, 2014
Author(s)
Hyuk-Jae Jang, Sujitra J. Pookpanratana, Alyssa N. Brigeman, Regis J. Kline, James I. Basham, David J. Gundlach, Christina A. Hacker, Oleg A. Kirillov, Oana Jurchescu, Curt A. Richter
Organic semiconductors hold immense promise for the development of a wide range of innovative devices with their excellent electronic and manufacturing characteristics. Of particular interest are non-magnetic organic semiconductors that show unusual

Synthesis, transport properties, and electronic structure of Cu2CdSnTe4

June 26, 2014
Author(s)
Yongkwan Dong, Artem R. Khabibullin, Kaya Wei, Zhen-Hua Ge, Joshua B. Martin, James Salvador, Lilia Woods, George S. Nolas
A new stannite phase was synthesized and its temperature dependent transport properties were investigated. It is found that the electrical resistivity increases with increasing temperature. Hall and Seebeck coefficient measurements indicate Cu2CdSnTe4

A nonlinearity in permanent-magnet systems used in watt balances

June 25, 2014
Author(s)
Shisong Li, Stephan Schlamminger, Jon R. Pratt
In watt balances that employ permanent magnet systems to generate the magnetic flux the effects of the weighing current on the magnet systems can generate a systematic bias that can lead to an error in the result if not accounted for. In this article a

Interrelationship between Number of Mobile Protons, Diffusion Coefficient, and AC Conductivity in Superprotonic Conductors, CsHSO 4 and Rb 3 H(SeO 4 ) 2

June 25, 2014
Author(s)
Kazuya Kamazawa, Masashi Harada, Toru Araki, Yasumitsu Matsuo, Madhu Sudan Tyagi, Jun Sugiyama
Using quasielastic neutron scattering (QENS), we investigated proton dynamics for two superprotonic conductors, CsHSO 4 and Rb 2H(SeO 4) 2. In the superprotonic conducting phase, two translational proton motions were observed for the both compounds. Making

Author(s)
Regina R. Montgomery
The SRM Spotlight is a newsletter published by the Office of Reference Materials for users of NIST standard reference materials. The Spotlight announces new reference materials and provides information about their use. In addition, this newsletter contains

Vapor Phase Metal-Assisted Chemical Etching of Silicon

June 25, 2014
Author(s)
Owen J. Hildreth, Daniel R. Schmidt
This work introduces and explores vapor phase metal‐assisted chemical etching (VP‐MaCE) of silicon as a method to bypass some of the challenges found in traditional liquid phase metal‐assisted chemical etching (LP‐MaCE). Average etch rates for Ag, Au, and

LDPC Error Correction for Gb/s QKD

June 24, 2014
Author(s)
Alan Mink, Anastase Nakassis
Low Density Parity Check (LDPC) error correction is a one-way algorithm that has become popular for quantum key distribution (QKD) post-processing. Graphic processing units (GPUs) provide an interesting attached platform that may deliver Gb/s error

Modelling the vertical UL 94 test: Competition and collaboration between melt dripping, gasification and combustion

June 24, 2014
Author(s)
Florian Kempel, Bernhard Schartel, Julio M. Marti, Kathryn Butler, Riccardo Rossi, Sergio R. Idelsohn, Anja Hofmann
An experimental and numerical investigation of the impact of the additives bisphenol A bis(diphenyl phosphate) (BDP) and polytetrafluoroethylene (PTFE) on the fire behaviour of bisphenol A polycarbonate / acrylonitrile butadiene styrene (PC/ABS) in the

Measuring Freeze and Thaw Damage in Mortars Containing Deicing Salt Using a Low Temperature Longitudinal Guarded Comparative Calorimeter and Acoustic Emission (AE-LGCC)

June 23, 2014
Author(s)
Yaghoob Farnam, Dale P. Bentz, Aaron R. Sakulich, Daniel R. Flynn, Jason Weiss
Deicing salts are often applied to the surface of pavements and bridge decks in the winter to melt ice; thereby improving safety for the travelling public. In this paper, the influence of NaCl deicing salt on freezing and thawing temperatures of pore
