The Relation between Crystalline Phase, Electronic Structure and Dielectric Properties in High-K Gate Stacks

September 28, 2005
Author(s)
Safak Sayan, Mark Croft, Nhan Van Nguyen, Tom Emge, James R. Ehrstein, Igor Levin, John S. Suehle, Robert A. Bartynski, Eric Garfunkel
As high permittivity dielectrics approach use in metal-oxide-semiconductor field effect transistor (MOSFET) production, an atomic level understanding of their electronic, and dielectric properties are being rigorously examined. The valence and conduction

Microscale Heat Transfer at Low Temperatures

September 26, 2005
Author(s)
Ray Radebaugh
This paper discusses the fundamentals and applications of heat transfer in small space and time domains at low temperatures. The modern trend toward miniaturization of devices requires a better understanding of heat transfer phenomena in small dimensions

Retrieval System Evaluation

September 26, 2005
Author(s)
C E. Buckley, Ellen M. Voorhees
One of the primary motivations for TREC was to standardize retrieval system evaluation. Prior to TREC, there was little explicit discussion of what constituted a minimally acceptable experimental design, and no hard evidence to support any position. TREC

Simple UML Modeling to Improve the Development of Information Standards

September 24, 2005
Author(s)
Eric D. Simmon, John V. Messina, Arthur Griesser
Streamlining and Bulletproofing the Standards Development Process In the increasingly complex semiconductor fabrication environment capturing and transferring information throughout the product development cycle is critical. As the process of creating

High-accuracy near infrared wavelength and frequency reference developments at NIST

September 23, 2005
Author(s)
William C. Swann, Sarah L. Gilbert, Brian Washburn, Nathan R. Newbury
NIST research on near infrared frequency and wavelength references is presented. A new high accuracy wavelength calibration transfer standard, SRM 2519a, based on molecular absorption lines of H13C14N is described. Research on optical frequency combs

Nanometer Resolution Metrology with the NIST Molecular Measuring Machine

September 23, 2005
Author(s)
John A. Kramar
Nanometre accuracy and resolution metrology over technically relevant areas is becoming a necessity for the progress of nanomanufacturing. At the National Institute of Standards and Technology, we are developing the Molecular Measuring Machine, a scanned

Airtightness of Commercial Buildings in the United States

September 21, 2005
Author(s)
Steven J. Emmerich, Andrew K. Persily
In 1998, Persily published a review of commercial and institutional building airtightness data that found significant levels of air leakage and debunked the myth of the airtight commercial building. This paper updates the earlier analysis for the U.S. by

Progress Toward Practical AC and DC Josephson Voltage Standards at NIST

September 21, 2005
Author(s)
Samuel Benz, Charles J. Burroughs, Paul Dresselhaus, Nicolas Hadacek, Yonuk Chong
For the past 10 years NIST has been developing the next generation of voltage standard systems based on arrays of normal-metal barrier Josephson junctions. We have developed stable, programmable dc standards capable of providing intrinsically stable

HEB FPA Imaging Technology for Security and Biomedical Applications

September 19, 2005
Author(s)
Eyal Gerecht, Dazhen Gu, Sigfrid Yngvesson, Fernando Rodriguez-Morales, Ric Zannoni, John Nicholson
We have demonstrated a low-noise heterodyne three-element focal plane array (FPA) at 1.6 THz consisting of NbN Hot Electron Bolometric (HEB) detectors, intimately integrated with MMIC IF amplifiers in a single block. HEB technology is becoming the basis

Energy Balance in a Large Compartment Fire. (POSTER ABSTRACTS)

September 18, 2005
Author(s)
Anthony P. Hamins, Erik L. Johnsson, Michelle K. Donnelly
The experiments described here were part of an international collaborative project to assess and validate fire computer codes for nuclear power plant applications. Understanding the distribution of energy released by a fire is important for testing the

Experiments and Modeling of Unprotected Structural Steel Elements Exposed to a Fire

September 18, 2005
Author(s)
Anthony P. Hamins, Kevin B. McGrattan, Kuldeep R. Prasad, Alexander Maranghides, Therese P. McAllister
A large-scale fire experiment was conducted to assess the accuracy of a combination of gas and solid-phase models designed to predict the temperatures of structural steel elements exposed to a fire. The experiment involved a 2 MW heptane spray fire in a
