Interfacial Properties of ZrO 2 on Silicon

May 15, 2003
Author(s)
Y S. Lin, R Puthenkovilakam, J Chang, Charles E. Bouldin, Igor Levin, Nhan Van Nguyen, James R. Ehrstein, Ying Sun, P Pianetta, T Conard, Wilfried Vandervorst, V Venturo, S Selbrede

Iron and Permalloy Based Magnetic Monolithic Tunable Microwave Devices

May 15, 2003
Author(s)
Bijoy Kuanr, Leszek Malkinski, Robert E. Camley, Zbigniew Celinski, Pavel Kabos
We constructed a series of Magnetic Monolithic tunable Microwave notch-filters and phase shifters in co-planer waveguide (CPW) geometry on GaAs substrates using Fe and Permalloy as magnetic materials. In contrast to previous work with Molecular Beam

National Institute of Standards and Technology (Handbook Chapter)

May 15, 2003
Author(s)
Joan Hash
The submission is a chapter describing NIST security standards (FIPS and Special Publication series 800). The author's instructions were that NIST prepare chapter summarizing standards indicating title, dates, publications, and brief summaries.

Next Generation Fire Suppression Technology Program: Fy2003 Progress

May 15, 2003
Author(s)
Richard G. Gann
The Department of Defense's Next Generation Fire Suppression Technology Program (NGP) has completed its sixth year of research with a goal to develop and demonstrate technology for economically feasible, environmentally acceptable and user-safe processes

Nucleation and Evolution of Hybrid Spin Spiral in Soft/Hard Ferromagnetic Bilayer

May 15, 2003
Author(s)
Yury P. Kabanov, V S. Gornakov, Valerian I. Nikitenko, Alexander J. Shapiro, Robert D. Shull
The hybrid exchange spring behavior in a bilayer consisting of an epitaxial film of Fe (500 A)/Smu2^}Co 7}(350 A) deposited onto a Cr(200 A) buffered MgO(110) substrate was investigated using the magneto-optical indicator film technique. Two critical

Room Temperature Active Regenerative Magnetic Refrigeration: Magnetic Nanocomposites

May 15, 2003
Author(s)
F Shir, L Yanik, Lawrence H. Bennett, Edward Della Torre, Robert D. Shull
Nanocomposites have several advantages as a refrigerant for 100 -300 K applications, compared to the other common methods of assembling a magnetic refrigeration bed, such as a layered arrangement of the thermal bed or mixing of different magnetic materials

Measuring the Invasiveness of High-Impedance Probes

May 14, 2003
Author(s)
Uwe Arz, Pavel Kabos, Dylan Williams
We use on-wafer measurements to characterize the invasiveness of high-impedance probes over a broad frequency range. We show that a two-port representation characterizing the invasiveness of the probe can also be determined from a calculation of the probe

Hierarachical Restoration Scheme for Multiple Failures in GMPLS Networks

May 12, 2003
Author(s)
Sanghun Lee, C Kim, David W. Griffith
It is expected that GMPLS-based recovery could become a viable option for obtaining faster restoration than layer 3 rerouting. Even though dedicated restoration ensures restorability of connections, exclusive use of dedicated scheme would result in wasting

Impact of Substrate Hot Hole Injection on Ultra-thin Silicon Dioxide Breakdown

May 12, 2003
Author(s)
Da-Wei Heh, Eric M. Vogel, J B. Bernstein
The impact of hot holes on gate oxide breakdown is studied by investigating devices under constant voltage stress with different amount of pre-injected substrate hot holes. The results show that oxide breakdown is independent of the amount of those pre

Initial Graphics Exchange Specification Volume 2: Application Protocols

May 12, 2003
Author(s)
Curtis H. Parks
This document brings together the fundamental contents of application protocols (AP) developed by the Initial Graphics Exchange Specification (IGES) Organization and approved as American National Standards (ANS) by the IGES Product Data Exchange using STEP

Reactive Molecular Dynamics Model of Thermal Decomposition in Polymers

May 11, 2003
Author(s)
Stanislav I. Stoliarov, Marc R. Nyden, R E. Lyon
The application of quantum chemical and molecular simulation methods can reveal new insights into the thermal degradation chemistries of materials. This work presents and employs an extension of classical force-field-based molecular dynamics to modeling

Atomic vapor cells for miniature frequency references

May 8, 2003
Author(s)
Svenja A. Knappe, V. Velichansky, Hugh Robinson, Li-Anne Liew, John M. Moreland, John Kitching, Leo W. Hollberg
We report on the fabrication of millimeter-sized vapor cells and their performance on atomic clocks based on coherent population trapping (CPT). We discuss two fabrication techniques, the first one based on hollow-core pyrex fibers, fused with a CO 2 laser

Atoms on Demand: Fast, Deterministic Production of Single Cr Atoms

May 5, 2003
Author(s)
S Hill, Jabez J. McClelland
We have realized a method for producing single Cr atoms on demand by suppressing the stochastic nature of the loading and loss processes of a magneto-optic trap. We observe single-atom trap occupation probabilities as high as (98.7 plus or minus} 0.1)% and
