Evaluation of Thin Film Mechanical Properties by Means of Electrical Test Methods

September 30, 2007
Author(s)
Nicholas Barbosa, Robert Keller, David T. Read, Richard P. Vinci
The ability to measure the mechanical properties of thin films and small scale structures is essential in designing reliable components at the micro- and nano-scales. It is known that the mechanical properties of thin film materials deviate from relations

Internal Photoemission Spectroscopy of Metal Gate/High-k/ Semiconductor Interfaces

September 30, 2007
Author(s)
Nhan V. Nguyen, Oleg A. Kirillov, Hao Xiong, John S. Suehle
Internal photoemission (IPE) spectroscopy is a powerful technique for investigating electronic properties of inhomogeneous interfaces of hetero-structures. Two most important aspects of IPE measurements involve threshold spectroscopy and photoelectron

Methods to Characterize the Electrical and Mechanical Properties of Si Nanowires

September 30, 2007
Author(s)
Qiliang Li, Sang-Mo Koo, Hao Xiong, Monica D. Edelstein, John S. Suehle, Xiaoxiao Zhu, D. E. Ioannou, Curt A. Richter
We report metrology methods to characterize nanowires. In this work, representative devices and test structures, including nanoelectromechanical switches, non-volatile nanowire memory devices with SONOS structure, and both transfer-length-method and Kelvin

NIST Microwave Scattering Parameter and Power Measurement Services

September 30, 2007
Author(s)
Ronald A. Ginley
This paper describes the microwave scattering parameter (s-parameter) and power measurement services available at NIST. This includes what is measured in each of the services, the techniques used for both calibration of the systems and subsequent

Obtaining Molecular Thermochemistry From Calculations

September 30, 2007
Author(s)
Karl K. Irikura
There are several computational approaches for predicting gas-phase, molecular thermochemistry. For common organic compounds, empirical methods are quick to compute and have been effectively parameterized. For uncommon compounds, the relative robustness of

Scanning Kelvin Force Microscopy For Characterizing Nanostructures in Atmosphere

September 30, 2007
Author(s)
Joseph Kopanski, Muhammad Afridi, Stoyan Jeliazkov, Weirong Jiang, Thomas R. Walker
The Electrostatic Force Microscope (EFM) and its variants are of interest for the measurement of potential distributions within nanostructures, and for work function measurements of gate metals for next generation CMOS. In phase mode, the EFM measures

The Characterization of Silicon-Based Molecular Devices

September 30, 2007
Author(s)
Nadine Gergel-Hackett, Christina Hacker, Lee J. Richter, Oleg A. Kirillov, Curt A. Richter
In order to realize molecular electronic (ME) technology, an intermediate integration with more traditional silicon-based technologies will likely be required. However, there has been little effort to develop the metrology needed to enable the fabrication

The Decontamination for Building Plumbing Systems - Analysis and Procedures

September 30, 2007
Author(s)
Stephen J. Treado
This report describes the results of measurements and analysis of methods to decontaminate building plumbing systems in the event of the accidental or intentional introduction of undesirable substances via the water supply system. The work described was

Conformance Test Suite for CBEFF Biometric Information Records

September 29, 2007
Author(s)
Yooyoung Lee, Fernando L. Podio, Mark Jerde
Deployment of standards-based biometric technologies is expected to significantly raise levels of security for critical infrastructures that has not been possible to date with other technologies. These systems require a comprehensive set of technically

Fab-wide Network Time Synchronization - Simulation and Analysis

September 28, 2007
Author(s)
Naveen Kalappa, Vinod Anandarajah, Julien L. Baboud, Ya-Shian Li-Baboud, James Moyne
In today?s fabs, coordination of time-based information throughout the factory and enterprise has become necessary. This has driven the need to have time synchronization at all levels of the enterprise. Time synchronization protocols such as Network Time

Improving the Common Vulnerability Scoring System

September 28, 2007
Author(s)
Peter M. Mell, Karen A. Scarfone
The Common Vulnerability Scoring System is an emerging standard for scoring the impact of vulnerabilities. This paper presents the results of our analysis of the scoring system and the results of our experiment scoring a large set of vulnerabilities using

Maze Hypothesis Development in Assessing Robot Performance During Teleoperation

September 28, 2007
Author(s)
Salvatore P. Schipani, Elena R. Messina
National Institute of Standards and Technology (NIST) personnel had the opportunity to assess 14 prospective Urban Search and Rescue (USAR) robots, for the purposes of developing performance standards which currently do not exist. During this exercise, a

Passive Cooling of a Micromechanical Oscillator with a Resonant Electric Circuit

September 28, 2007
Author(s)
Kenton R. Brown, Joseph W. Britton, Ryan Epstein, John Chiaverini, Dietrich G. Leibfried, David J. Wineland
Currently there is considerable interest in the cooling of macroscopic mechanical oscillators, as strong cooling may allow one to reach the quantum regime of such oscillators. Recent advances in microfabrication and cooling techniques have brought this

Analysis of Thermocouple Behavior in Compartment Fires

September 27, 2007
Author(s)
Sung C. Kim, Anthony P. Hamins, Matthew F. Bundy, Gwon Ko, Erik L. Johnsson
The present study uses numerical simulations and analytical solutions to investigate the heat transfer processes associated with bare bead and double shield aspirated thermocouples. The uncertainty of thermocouple temperature measurements is emphasized

Effect of Lubricant on R410A Horizontal Flow Boiling

September 27, 2007
Author(s)
N N. Sawant, Mark A. Kedzierski, J S. Brown
The paper experimentally quantified the effect of lubricant on horizontal flow boiling of R410A. This was accomplished by first establishing a baseline by measuring the convective boiling heat transfer performance of pure R410A. The heat transfer
