Daniel Josell, Carlos R. Beauchamp, Behrang H. Hamadani, Suyong S. Jung, Jonathan E. Guyer, Abhishek Motayed, Carlos M. Hangarter, Nadine E. Gergel-Hackett, Hua Xu, Nikolai B. Zhitenev
Fabrication and properties of three-dimensionally structured back-contact heterojunction solar cells are described. A variety of devices are explored, all of which were fabricated by electrochemical deposition of a semiconducting material on one of two

Wildfire Prevention Efficacy: Marginal and Non-marginal Benefit-Cost Ratios

February 1, 2010
Author(s)
Jeffrey P. Prestemon, David Butry, Karen L. Abt, Rhonda Sutphen
Fire prevention education efforts involve a variety of methods intended to reduce the number of accidentally ignited wildfires, including public service announcements, distributing brochures and making presentations. A Poisson model of Florida fire

NIST HB 105-3, Specifications and Tolerances for Reference Standards and Field Standard Weights and Measures, 3. Specifications and Tolerances for Graduated Neck Type Volumetric Field Standards

January 31, 2010
Author(s)
Georgia L. Harris, L.F. Eason
These specifications and tolerances are recommended as minimum requirements for standards used by state and local weights and measures officials and others in the regulatory verification of meters used in quantity determination of liquid commodities. Other

Infrared time domain spectroscopy with synchronized frequency combs

January 29, 2010
Author(s)
Nathan R. Newbury, Ian R. Coddington, William C. Swann
We describe a frequency-comb based system for time-domain spectroscopy in the near infrared. Our configuration implements synchronous, repetitive sampling of the time domain signature for real-time coherent signal averaging and improved signal-to-noise

January 29, 2010
Author(s)
Mark D. Stolorow
This document constitutes the 2-Year Road Map FY 2009 - 2011 for the Office of Law Enforcement Standards (OLES), Electronic and Electrical Engineering Laboratory (EEEL), National Institute of Standards and Technology.

Office of Law Enforcement Standards Strategic Planning FY2009-2018.

January 29, 2010
Author(s)
Mark D. Stolorow
This document constitutes the ten-year Strategic Plan for FY2009-2018 for the Office of Law Enforcement Standards (OLES), Electronic and Electrical Engineering Laboratory (EEEL), National Institute of Standards and Technology.

Rationales and Mechanisms for Revitalizing US Manufacturing R&D Strategies

January 29, 2010
Author(s)
Gregory C. Tassey
The race to economic superiority is increasingly occurring on a global scale. Competitors from different countries are employing new types of growth strategies in attempts to win that race. The United States cannot, therefore, continue to rely on outdated

Spin-transfer dynamics in spin valves with out-of-plane magnetized CoNi free layers

January 29, 2010
Author(s)
William H. Rippard, Alina M. Deac, Matthew R. Pufall, Justin M. Shaw, Mark W. Keller, Stephen E. Russek, Gerrit E. Bauer, Claudio Serpico
We have measured spin-transfer-induced dynamics in magnetic nanocontact devices having a perpendicularly magnetized Co/Ni free layer and an in-plane magnetized CoFe fixed layer. The frequencies and powers of the excitations agree well with the predictions

Quantum Computing

January 28, 2010
Author(s)
Emanuel H. Knill
Imagine a computer that can exploit quantum mechanics to solve previously intractable problems in physics, mathematics and cryptography. Such a quantum computer would revolutionize computing technology while teaching us about fundamental physics and ways

Quantification of the Binding Affinity of a Specific Hydroxyapatite Binding Peptide

January 27, 2010
Author(s)
Michael C. Weiger, Jung Jin Park, Marc D. Roy, Christopher M. Stafford, Alamgir Karim, Matthew L. Becker
The genesis of bone and teeth results from highly coordinated processes which involve several cell types, proteins which direct the nucleation and crystallization of inorganic hydroxyapatite (HA). Recent studies have shown that engineered peptide sequences

Comparison Testing Protocol for Firebrand Penetration through Building Vents: Summary of BRI/NIST Full Scale and NIST Reduced Scale Results

January 25, 2010
Author(s)
Samuel L. Manzello, Seul-Hyun Park, John R. Shields, Yoshihiko Hayashi, Sayaka Suzuki
An ASTM task group on vents, organized within Subcommittee E05.14.06, External Fire Exposures, has developed a reduced scale test method (not presently a standard) aimed at evaluating the ability of vents to resist firebrand intrusion into attic and crawl

Linewidth narrowing and Purcell enhancement in photonic crystal cavities on an Er-doped silicon nitride platform

January 25, 2010
Author(s)
Yiyang Gong, Maria Makarova, Selcuk Yerci, Rui Li, Martin Stevens, Burm Baek, Sae Woo Nam, Robert Hadfield, Sander N. Dorenbos, Val Zwiller, Luca Dal Negro, Jelena Vuckovic
Light emission at 1.54 mm from an Er-doped amorphous silicon nitride layer coupled to photonic crystal resonators at cryogenic and room temperatures and under varying optical pump powers has been studied. The results demonstrate that small mode volume

Resistivity Dominated by Surface Scattering in Sub-50 nm Cu Wires

January 25, 2010
Author(s)
Rebekah L. Graham, Glenn Alers, Thomas Mountsier, N. Shamma, S. Dhuey, R. H. Cabrini, Roy H. Geiss, David T. Read, S. Peddeti
The electron scattering mechanisms in sub-50nm copper lines were investigated to understand the extendibility of copper interconnects when the line width or thickness is less than the mean free path. Electron-beam lithography and a dual hardmask approach

Effect of Heat Pump Commissioning Faults on Annual Energy Use

January 24, 2010
Author(s)
Piotr A. Domanski, Hugh Henderson, William V. Payne
The study sought to develop an understanding of the impact of commissioning common faults the energy consumption of an air-to-air heat pump installed in a single-family house. Through annual simulations of the house/heat pump system, the study found that

Ergodic Convergence Times For Molecular Liquids

January 22, 2010
Author(s)
Raymond D. Mountain
A problem common to all molecular dynamics and Monte Carlo simulations used to estimate fluid properties is how to decide when adequate sampling of the phase space of the system has been realized. One procedure for addressing the sampling question is to
