Asymmetric Energy Distribution of Interface Traps in n- & p- MOSFETs with HfO2 Gate Dielectric on Ultra-thin SiON Buffer Layer

March 1, 2004
Author(s)
Jin-Ping Han, Eric M. Vogel, Evgeni Gusev, C. D'Emic, Curt A. Richter, Da-Wei Heh, John S. Suehle
The variable rise/fall-time charge pumping technique has been used to determine the energy distribution of interface trap density (Dit) in MOSFETs with HfO2 gate dielectric grown on ultra-thin (1-2 monolayer) SiON buffer layer on Si. Our results have

Automated Composition of Conversion Software

March 1, 2004
Author(s)
David W. Flater
Given a library of converters with known behaviors, an integration engine must determine which are useful in a given scenario and produce a plan for how they can be used to achieve specified goals. This report documents the algorithm implemented by the

Brillouin Scattering Studies of Polymeric Nanostructures

March 1, 2004
Author(s)
R Hartschuh, A Mahorowala, Y Ding, J H. Roh, A Kisliuk, Alexei Sokolov, Christopher Soles, Ronald L. Jones, T J. Hu, Wen-Li Wu
Polymers are now being patterned into nanometer-sized features via optical and/or imprint lithography for a range of applications, including semiconductors, Micro-Electro- Mechanical systems (MEMS), and Nano-Electro-Mechanical systems (NEMS). In these

Card Technology Developments and Gap Analysis Interagency Report

March 1, 2004
Author(s)
William C. Barker, Deborah Howard, Timothy Grance, Levent Eyuboglu
This Card Technology Developments and Gap Analysis Interagency Report (IR) provides information regarding current technical capabilities and limitations of storage and processor cards, current user requirements for individual and integrated technologies

Cell Seeding into Calcium Phosphate Cement

March 1, 2004
Author(s)
Carl Simon Jr., William F. Guthrie, Francis W. Wang
We have sought to improve calcium phosphate cement by developing a method for seeding bone cells into the cement. Calcium phosphate cement (CPC) is a dry white powder of calcium phosphate salts that when mixed with water will react to form microcrystalline

Characterization of Poly(L-Lysine)-graft-Poly (Ethylene Glycol) Assembled Monolayers on Niobium Pentoxide Substrates Using Time-of-Flight Secondary Ion Mass Spectrometry and Multivariate Analysis

March 1, 2004
Author(s)
M S. Wagner, S Pasche, David G. Castner, M Textor
Control of protein adsorption onto solid surfaces is a critical area of biomaterials and biosensors research. Application of high performance surface analysis techniques to these problems can improve the rational design and understanding of coatings that

Continuous-Wave Terahertz Spectroscopy of Plasmas and Biomolecules

March 1, 2004
Author(s)
David F. Plusquellic, T M. Korter, Gerald T. Fraser, R J. Lavrich, Eric C. Benck, C R. Bucher, Angela R. Hight Walker, J L. Domenech
Continuous-wave linear-absorption spectroscopy based on THz radiation generated by solid-state photomixers has been applied to the investigation of the dynamics of biomolecules in polyethylene matrices and to line shape studies of HF for diagnostics of

Cost-Effective Responses to Terrorist Risks in Constructed Facilities

March 1, 2004
Author(s)
Robert E. Chapman, C J. Leng
The owners and managers of constructed facilities face the challenge of responding to potential future terrorist attacks in a financially responsible manner. The Office of Applied Economics (OAE) in the Building and Fire Research Laboratory at the National

Energy Analysis of Multi-Lens Adhesion Measurements

March 1, 2004
Author(s)
Aaron M. Forster, Christopher Stafford, Alamgir Karim
The NIST Combinatorial Methods Center (NCMC) has adapted the Johnson Kendall, and Roberts (JKR) adhesive contact test for the development of a high-throughput adhesion measurement platform. This technique utilizes an array of hemispherical lenses to

Federal Information Processing Standard (FIPS) 199, Standards for Security

March 1, 2004
Author(s)
Shirley M. Radack
This ITL Bulletin describes FIPS 199, Standards for Security Categorization of Federal Information and Information Systems, which is an important component of a suite of standards and guidelines that NIST is developing to improve the security in federal

Finite-Size Effects on Surface Segregation in Polymer Blend Films Above and Below the Critical Point of Phase Separation

March 1, 2004
Author(s)
H Grull, Li Piin Sung, Alamgir Karim, Jack F. Douglas, Sushil K. Satija, Makoto Hayashi, H Jinnai, TT Hashimoto, Charles C. Han
We investigate the influence of temperature and confinement on surface segregation in thin films of deuterated polybutadiene and polyisoprene near the critical point for phase separation. Neutron reflectivity measurements show that polyisoprene enriches at

Flow Simulation of a Microfluidic Analog of the Four-Roll Mill

March 1, 2004
Author(s)
Frederick R. Phelan Jr., Steven Hudson
The fluid dynamics of channel geometries for liquid state materials characterization in microfluidic devices are investigated using finite element flow simulation and flow classification criteria. A pressure driven microchannel device is sought that has an

Fracture Mirrors in a Nanoscale 3Y-TZP

March 1, 2004
Author(s)
George D. Quinn, J Eichler, U Eisele, J Rodel
The strengths of fine microstructural scale yttria stabilized rectangular bars and circular disks were measured by four-point flexure and by flat ball (piston) on three ball methods. Fracture mirror sizes were measured and correlated to the strengths
