Synchrotron Methods for Flexible Hybrid Electronics Industrial Recommendations on Interagency (DoC-DoD-DoE) Partnerships to Address Measurement Challenges Hindering the Flexible Hybrid Electronics Manufacturing Ecosystem

February 12, 2018
Author(s)
Christopher L. Soles, Richard A. Vaia, Ronald Pindak
The round-table participants concluded that facilities at NSLS-II provide immediate opportunities to address some of the critical processing and measurement challenges that are blocking the path towards a sustainable US-centric Flexible Hybrid Electronic

STM patterned nanowire measurements using photolithographically defined implants in Si(100)

January 29, 2018
Author(s)
Aruna N. Ramanayaka, Hyun Soo Kim, Ke Tang, Xiqiao Wang, Richard M. Silver, Michael D. Stewart, Joshua M. Pomeroy
Using photolithographically defined implant wires for electrical connections, we demonstrate measurement of a scanning tunneling microscope (STM) patterned nanoscale electronic device on Si(100), eliminating the onerous alignment procedures and electron

Highly Efficient Rapid Annealing of Thin Polar Polymer Film Ferroelectric Devices at Sub-Glass Transition Temperature

December 18, 2017
Author(s)
Vasileia Georgiou, Dmitry Veksler, Jason T. Ryan, Jason P. Campbell, Pragya R. Shrestha, D. E. Ioannou, Kin P. Cheung
An unexpected rapid anneal of electrically active defects in an ultra-thin (15.5 nm) polar polyimide film at and below glass transition temperature (Tg) is reported. The polar polymer is the gate dielectric of a thin-film-transistor (TFT). Gate leakage

Electromagnetic Scattering from Individual Crumpled Graphene Flakes: A Characteristic Modes Approach

September 14, 2017
Author(s)
Edward J. Garboczi, Jack F. Douglas, Luis Fernando Vargas Lara, Ahmed M. Hassan, Deb Chatterjee, Kalyan Durbhakula, Md Gaffar
Graphene flakes in real composites are rarely perfectly flat, and often exhibit complicated crumpled shapes. Therefore, the goal of this work was to quantify the electromagnetic scattering characteristics of individual crumpled graphene flakes with shapes

Microstructure Knowledge Systems for Capturing Process-Structure Evolution Linkages

June 14, 2017
Author(s)
James A. Warren, Daniel Wheeler, David Brough, Surya Kalidindi
This paper develops and demonstrates a novel data science framework for capturing and communicating critical information regarding the evolution of material structure in spatiotemporal multiscale simulations of various processing operations employed by the

Software Tools for Uncertainty Evaluation in VNA Measurements: A Comparative Study

June 8, 2017
Author(s)
Gustavo Avolio, Dylan Williams, Michael Frey, Sarah B. Streett, Dominique Schreurs, Andrea Ferrero, Michael Dieudonne
We compared three software tools designed for scattering-parameter measurement uncertainty evaluation. These tools propagate uncertainty to calibrated S-parameters by means of a sensitivity analysis. We also validated the sensitivity analysis with Monte

Resonant Acoustic Frequency Shifts Associated with Cracks in Multilayer Ceramic Capacitors

June 6, 2017
Author(s)
Ward L. Johnson, Jaemi Herzberger, Sudook A. Kim, Kirsten L. Peterson, Paul R. Heyliger, Grady S. White
Resonant ultrasound spectroscopy (RUS) was used in this study to measure shifts in resonant frequency that arise from the presence of cracks in barium-titanate-based multi-layer ceramic capacitors (MLCCs). This work was motivated by an industrial need for

Dynamic Appliances Scheduling in Collaborative MicroGrids System

May 1, 2017
Author(s)
Hamid Gharavi, Hasnae Bilil
Abstract—In this paper a new approach which is based on a collaborative system of MicroGrids (MG’s), is proposed to enable household appliance scheduling. To achieve this, appliances are categorized into flexible and non-flexible Deferrable Loads (DL’s)

Life Time Dosimetric Assessment for Mice and Rats Exposed to Cell Phone Radiation in Reverberation Chambers

March 17, 2017
Author(s)
Perry F. Wilson, John M. Ladbury, Galen H. Koepke, Yijian Gong, Myles Capstick, Keven Kuhn, David L. McCormick, Ronald L. Melnick, Niels Kuster
In this paper, we present a detailed life time dosimetry analysis for individually housed rodents exposed to radio frequency (RF) signals. The unrestrained rodents were exposed in reverberation chambers for 2 years at three whole-body averaged specific

2016 PSCR Analytics Summit Report

January 30, 2017
Author(s)
Jeremy E. Benson, Harris Feldman
PSCR hosted over 80 stakeholders from industry, academia, public safety, and government to the NIST Boulder campus in August 2016. The August summit was a follow-up to the Public Safety Analytics R&D Roadmap, published earlier in 2016. This document

Foreword

January 2, 2017
Author(s)
Sokwoo Rhee
For IoT to be broadly adopted, it is important to apply the concept to many applications at scale in our everyday life. Using these advanced technologies, our communities and cities can be more intelligent, secure, and resilient. The Hardware and

Trapping States of Mixed-Isomer Organic Semiconductors within Organic Field-Effect Transistors

December 14, 2016
Author(s)
Peter Diemer, Jacori Hayes, Evan Welchman, Rawad Hallani, Sujitra Pookpanratana, Christina Hacker, Curt A. Richter, Timo Thonhauser, Oana Jurchescu
Organic field effect transistor (OFET) performance is dictated by the composition and geometry of the device, as well as the quality of the organic semiconductor (OSC) film, which strongly depends on the purity and structural defects. When present, these

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

Calibration of Time-interleaved Errors in Real-time Digital Oscilloscopes

November 1, 2016
Author(s)
Jeffrey A. Jargon, Chihyun Cho, Joo-Gwang Lee, Paul D. Hale, Peter J. Jeavons, John B. Schlager, Andrew M. Dienstfrey
A novel method is proposed for the calibration of channel mismatch in a time-interleaved real- time digital oscilloscope (RTDO). A simple simultaneous equation is derived from the Fourier transform of the time-interleaved signals requiring only a transfer

Model Verification with Measurement Uncertainty

Author(s)
Dylan F. Williams, Richard A. Chamberlin, Jerome G. Cheron, Wei Zhao, Urteaga Miguel
We verify a model for state-of-the-art 250 nm heterojunction bipolar transistors with large-signal measurements. We demonstrate the propagation of correlated measurement uncertainties through the model-extraction and verification process, and use them to
