Computer-Controlled Characterization of High-Voltage, High-Frequency SiC Devices

July 1, 2006
Author(s)
Jose M. Ortiz-Rodriguez, Allen R. Hefner Jr., David W. Berning, Colleen E. Hood, S. Olcum
Silicon carbide (SiC) power devices have begun to emerge recently with a performance that is superior to that of silicon power devices. Therefore, the push to higher power and higher voltage applications also comes with it. This work addresses the need for

Direct Josephson Array Voltage Comparison Between NRC and NIST

July 1, 2006
Author(s)
Barry Wood, Yi-hua D. Tang, Clark A. Hamilton
The National Research Council's (NRC) Josephson voltage standard (JVS) has been directly compared with the compact, transportable Josephson array standard of the National Institute of Standards and Technology (NIST) at 10 V. A simplified biasing technique

Efficient Circuits for Exact-Universal Computation With Qudits

July 1, 2006
Author(s)
G K. Brennen, Stephen Bullock, Dianne M. O'Leary
This paper concerns the efficient implementation of quantum circuits for qudits. We show that controlled two-qudit gates can be implemented without ancillas and prove that the gate library containing arbitrary local unitaries and one two-qudit gate, CINC

Elastic Moduli of Ultrathin Amorphous Polymer Films

July 1, 2006
Author(s)
Christopher Stafford, C Harrison, D Julthongpiput, B D. Vogt
The elastic moduli of ultrathin poly(styrene) and poly(methylmethacrylate) films of thickness ranging from 200 nm to 5 nm were investigated using a buckling-based metrology. Below 40 nm, the apparent modulus of the PS and PMMA films decreases dramatically

Elimination of pump-induced frequency jitter on fiber-laser frequency combs

July 1, 2006
Author(s)
John J. McFerran, William C. Swann, Brian R. Washburn, Nathan R. Newbury
Optical frequency combs generated by femtosecond fiber lasers typically exhibit significant frequency noise that causes broad optical linewidths, particularly in the comb wings and in the carrier-envelope offset frequency (fceo) signal. We show these broad

Extended EUV and UV Spectrum of Ne II

July 1, 2006
Author(s)
Alexander Kramida, C M. Brown, Uri Feldman, Joseph Reader
The extreme ultraviolet (EUV) spectrum of Ne emitted by a Penning discharge has been recorded at high resolution with a 10.7 m grazing incidence spectrometer. Based on the recorded spectra 75 new Ne II lines have been observed between 286 and 325

Growth of Nanocrystalline Ceria Studied Using a USAXS Capillary Flow-Cell

July 1, 2006
Author(s)
Vincent A. Hackley, Andrew J. Allen, P R. Jemian, J M. Raitano, S W. Chan
Nanocrystalline ceria particles, with dimensions as small as 2 nm, have been prepared at room temperature by a soft chemical route using aqueous cerium nitrate and hexamethylenetetramine (HMT) as reactants. HMT decomposes slowly in aqueous solution

Laser Transition Probabilities in Xe I

July 1, 2006
Author(s)
Abhijit Dasgupta, J P. Apruzes, O Zatsarinny, K Bartschat, Charlotte F. Fischer
The atomic xenon laser is among the most efficient and powerful of the near-infrared gas lasers, especiallywhen pumped by molecular ions in an Ar-Xe mixture. Accurate transition probabilities for the laser transitionsare critical in developing a

Methods to Characterize Ricin for the Development of Reference Materials

July 1, 2006
Author(s)
Sung Kim, Diane K. Hancock, Lili Wang, Kenneth D. Cole, Prasad T. Reddy
Ricin is an abundant protein from the castor bean plant Ricinus communis. Because of its high toxicity and the simplicity of producing mass quantities, ricin is considered a biological terrorism agent. We have characterized ricin extensively with a view to

Modeling and Simulation of Nanometer Scale Copper Resistivity

July 1, 2006
Author(s)
Emre Yarimbiyik, Harry A. Scahfft, Richard A. Allen, Mona E. Zaghloul
A highly flexible simulation program to calculate the resistivity of thin films and lines with various line widths has been developed. The program takes into account the effect of surface and grain boundary scatterings, as well as temperature, on

Multi-path Multi-Channel Routing Protocol

July 1, 2006
Author(s)
Bo Yan, Hamid Gharavi
In this paper we present a DSR-based multi-path Routing protocol, which has been developed for transmission of Multiple Description Coded (MDC) packets in wireless ad-hoc network environments. The protocol is designed to eliminate co-channel interference

NCMC Workshop ReportNCMC-9: Combinatorial Methods for Nanostructured Materials

July 1, 2006
Author(s)
Michael J. Fasolka, Carol E. Laumeier
NCMC-9: Combinatorial Methods for Nanostructured Materials was a forum to examine the application and development of nanostructured materials by industry, with a focus on polymeric products, such as films, coatings and paints, adhesives, and personal care

New reference standards and artifacts for nanoscale physical property characterization

July 1, 2006
Author(s)
Jon R. Pratt, John A. Kramar, Gordon Shaw, Richard Gates, Paul Rice, John M. Moreland
This paper provides an overview of calibration artifacts being developed at the National Institute of Standards and Technology (NIST) that are intended to aid the accurate determination of nanoscale physical properties across a broad range of applications

NIST Sampling System for Accurate Ac Waveform Parameter Measurements

July 1, 2006
Author(s)
David I. Bergman
This paper summarizes efforts at the National Institute of Standards and Technology to develop a waveform sampling and digitizing system with accuracy comparable to that of an ac-dc thermal transfer standard for ac voltage measurements over the frequency
