Adhesion loss due to moisture is a fundamental problem in a large diversity of industries ranging from microelectronics and automotive to aerospace. This study investigates the durability of model adhesive joints consisting of a homologous series of poly(n

NBTI: Why Won't This Thing Go Away?

October 19, 2009
Author(s)
Jason P. Campbell
The negative-bias temperature instability (NBTI) is a reliability problem that, in the last ten years, has risen from relative obscurity to become the most important reliability problem in advanced pMOSFET devices. Even though a significant effort has been

Magnetic Tunnel Junctions with Self-Assembled Molecules

February 5, 2009
Author(s)
Wenyong Wang, Curt A. Richter
Molecular electronic devices with spin-dependent tunneling (SDT) transport behavior offer an innovative and extremely enticing direction towards spin electronics, both from fundamental and technological points of view. In this work, such molecular magnetic

Extraction of Sheet Resistance and Line Width from All-Copper ECD Test Structures Fabricated from Silicon Preforms

November 3, 2008
Author(s)
Byron J. Shulver, Andrew S. Bunting, Alan Gundlach, Les I. Haworth, Alan W. Ross, Stewart Smith, Anthony J. Snell, J. T. Stevenson, Anthony Walton, Richard A. Allen, Michael W. Cresswell
Test structures have been fabricated to allow Electrical Critical Dimensions (ECD) to be extracted from copper features with dimensions comparable to those replicated in IC interconnect systems. The implementation of these structures is such that no

Roughness-Induced Superhydrophobicity: A Way to Design Non-Adhesive Surfaces

July 4, 2008
Author(s)
Michael Nosonovsky, Bharat Bhushan
Non-adhesive and water-repellent surfaces are required for many tribological applications. Roughness-induced superhydrophobicty has been suggested as a way to reduce adhesion and stiction. In this paper, the theory of roughness-induced superhydrophobicity

Correlation Between Microstructure, Electronic Properties and Ficker Noise in Organic Thin Film Transistors

March 31, 2008
Author(s)
Oana Jurchescu, Behrang H. Hamadani, Hao Xiong, Sungkyu Park, Sankar Subramanian, Neil M. Zimmerman, John E. Anthony, Thomas Jackson, David J. Gundlach
We report on observations of a direct correlation between the microstructure of the organic thin films and their electronic properties when incorporated in field-effect transistors. We present a simple method to induce enhanced grain growth in solution

Magnetic Levitation System for the Dissemination of a Non-Artifact Based Kilogram

November 27, 2007
Author(s)
Zeina J. Kubarych, Patrick J. Abbott, Edwin R. Williams, Ruimin Liu, Vincent J. Lee
We describe a new approach to directly link air and vacuum mass measurements. This approach uses magnetic levitation along with vacuum and balance technology to realize vacuum mass measurements. It provides direct traceability to the International

Method for estimating the dielectric constant of natural gas mixtures

January 11, 2005
Author(s)
Allan H. Harvey, Eric Lemmon
A method is developed for calculating the static dielectric constant (relative permittivity) of fluid mixtures, with an emphasis on natural gas. The dielectric constant is calculated as a function of temperature, density, and composition; the density is

Workshop Summary Report: Scanning Probe Nanolithography Workshop

January 1, 2003
Author(s)
John A. Dagata, H Yokoyama, F Perez-murano
A workshop on Scanning Probe Microscope (SPM)-based Nanolithography was held at NIST Gaithersburg on November 24-25, 2003. The meeting was sponsored by the Precision Engineering Division, Manufacturing Engineering Laboratory, NIST, under a Research

Highly Charged Ions

January 1, 2001
Author(s)
John D. Gillaspy
This article reviews some of the fundamental properties of highly charged ions, the methods of producing them (with particular emphasis on table-top devices), and their use as a tool for both basic science and applied technology. Topics discussed include

Building a Question Answering Test Collection

July 1, 2000
Author(s)
Ellen M. Voorhees, D M. Tice
The TREC-8 Question Answering (QA) Track was the first large-scale evaluation of domain-independent question answering systems. In addition to fostering research on the QA task, the track was used to investigate whether the evaluation methodology used for

Far-Infrared Two-Phonon Absorption in GaP and GaAs

Author(s)
Simon G. Kaplan, H M. Lawler, Eric L. Shirley, S Bhat, M E. Thomas
We present detailed temperature dependent absorption spectra of GaP and GaAs at wavenumbers from 20 cm-1 to 350 cm-1 and temperatures between 10 K and 295 K. Comparison of the experimental data with the predictions of recent ab initio anharmonic lattice

Elucidating the challenges in extracting ultra-slow flame speeds in a closed vessel - A CH2F2 microgravity case study using optical and pressure-rise data

Author(s)
Raik Hesse, Chaimae Bariki, Michael Hegetschweiler, Gregory T. Linteris, Heinz Pitsch, Joachim Beeckmann
Refrigerants with a low global warming potential (GWP) possess mild flammability. Hence, a fundamental understanding of their combustion characteristics is required to assess their fire-hazardous potential. The laminar burning velocity is one fundamental
