The 2016 revision of ISO 1 Standard reference temperature for the specification of geometrical and dimensional properties

November 10, 2016
Author(s)
Steven D. Phillips, Craig M. Shakarji, Alessandro Balsamo, Michael Krystek, Edward P. Morse
This paper discusses the recently published 2016 (third edition) of ISO 1. While the value of the standard reference temperature remains unchanged at 20 C, definitions for the reference temperature and standard reference temperature are now included. This

BLER Performance Evaluation of LTE Device-to-Device Communications

November 9, 2016
Author(s)
Jian Wang, Richard A. Rouil
Long-Term Evolution (LTE) supporting Device-to-Device (D2D) communication is a feature introduced in 3rd Generation Partnership Project (3GPP) release 12. D2D communication is critical in public safety applications, which enables communication among first

Towards a generalized energy prediction model for machine tools

November 9, 2016
Author(s)
Raunak Bhinge, Jinkyoo Park, Kincho H. Law, David Dornfeld, Moneer Helu, Sudarsan Rachuri
Energy prediction of machine tools can deliver many advantages to a manufacturing enterprise, ranging from energy-efficient process planning to machine tool monitoring. Physics-based energy prediction models have been proposed in the past to understand the

Assessing the Impact of NIST's Forensic Publications and Collaborations

November 8, 2016
Author(s)
Susan L. Makar, Amanda J. Malanowski
Forensics at the National Institute of Standards and Technology (NIST) crosses many disciplines and includes computer forensics, firearms analysis, trace analysis, and forensic biometrics, including fingerprints and DNA analysis. This research and the

Comparison of CBED and ABF Atomic Imaging for GaN Polarity Determination

November 8, 2016
Author(s)
Alexana Roshko, Matthew D. Brubaker, Paul T. Blanchard, Kristine A. Bertness, Todd E. Harvey, Igor Levin, R.H. Geiss
A comparison of two electron microscopy techniques used to determine the polarity of GaN nanowires is presented. The techniques are convergent beam electron diffraction (CBED) in TEM mode and annular bright field (ABF) imaging in aberration corrected STEM

The influence of the aromatic character in the gas chromatography elution order: the case of polycyclic aromatic hydrocarbons

November 8, 2016
Author(s)
Jorge O. Ona Ruales, Walter B. Wilson, Federica Nalin, Lane C. Sander, Patricia Schubert, Stephen A. Wise
A link between the aromatic character of polycyclic aromatic hydrocarbons (PAHs) and gas chromatography (GC) elution order in columns with a polysiloxane backbone in the stationary phase is reported for the first time. The aromatic character was calculated

VECSEL systems for generation and manipulation of trapped magnesium ions

November 8, 2016
Author(s)
Shaun C. Burd, David T. Allcock, Tomi Leinonen, Jussi-Pekka Penttinen, Daniel H. Slichter, Raghavendra Srinivas, Andrew C. Wilson, Robert Jordens, Micrea Guina, Dietrich G. Leibfried, David J. Wineland
Experiments in atomic, molecular, and optical (AMO) physics rely on lasers at many different wave- lengths and with varying requirements on spectral linewidth, power and intensity stability. Vertical external-cavity surface-emitting lasers (VECSELs), when

Circular Photogalvanic Effect in Organometal Halide Perovskite CH3NH3PbI3

November 7, 2016
Author(s)
Junwen Li, Paul M. Haney
We study the circular photogalvanic effect in the organometal halide perovskite solar cell absorber CH$_3$NH$_3$PbI$_3$. The calculated photocurrent density is about $10^{-9}$ A/W, comparable to the previously studied quantum well and bulk Rashba systems

Distinct Magnetic Spectra in the Hidden Order and Antiferromagnetic Phases in URu 2-x Fe x Si 2

November 7, 2016
Author(s)
Nicholas P. Butch, Sheng Ran, Inho Jeon, Noravee Kanchanavatee, Kevin Huang, Alexander Breindel, M. Brian Maple, Ryan L. Stillwell, Yang Zhao, Leland Weldon Harriger, Jeffrey W. Lynn
We use neutron scattering to compare the magnetic excitations in the hidden order (HO) and antiferromagnetic (AFM) phases in URu 2-xFe xFe xSi 2 as a function of Fe concentration. The magnetic excitation spectra change significantly between x=0.05 and x=0

Double Quantum Dot Floquet Gain Medium

November 7, 2016
Author(s)
Jacob M. Taylor, Michael Gullans, Jason Petta, J. Stehlik, Yinyiu Liu, Christopher Eichler, T Hartke, X Mi
A qubit coupled to a microwave resonator allows the study of fundamental light-matter interactions at the level of single photons1. The paradigm of circuit quantum electrodynam- ics (cQED) enables the generation of classical and non-classical light2–5

Tomography of a probe potential using atomic sensors on graphene

November 7, 2016
Author(s)
Jonathan E. Wyrick, Donat F. Natterer, Yue Y. Zhao, Kenji Watanabe, Takashi Taniguchi, William G. Cullen, Joseph A. Stroscio
One of the great advances in our ability to probe the quantum world has been the ability to manipulate the electronic structure of materials by constructing artificial nanostructures on surfaces using atomic manipulation of single adatoms with scanning

A Tetherless, Absolute-Time Channel Sounder, Processing, and Results for a Complex Environment

November 4, 2016
Author(s)
David R. Novotny, Alexandra E. Curtin, Catherine A. Remley, Peter B. Papazian, Jeanne T. Quimby, Richard Candell
we present a channel sounder that can operate without a tether and still maintain an absolute time reference between the source and receiver. Based on a sliding correlator, with synchronized rubidium clocks to generate phase references for the up- and down

Calibration of Effective Tunneling Bandgap in GaAsSb/InGaAs for improved TFET Performance Prediction

November 3, 2016
Author(s)
Quentin Smets, Anne S. Verhulst, Salim El Kazzi, David J. Gundlach, Curt A. Richter, Anda Mocuta, Nadine Collaert, Aaron Thean, Marc Heyns
The effective bandgap for heterojunction band-to-band tunneling (Eg,eff) is a crucial design parameter for heterojunction TFET. However, there is significant uncertainty on Eg,eff, especially for In0.53Ga0.47As/GaAs0.5Sb0.5. This makes TFET performance
