291. Elemental and Molecular Imaging of Human Hair Using Secondary Ion Mass Spectrometry
Topic: Nanotechnology
Published: 4/1/1999
Authors: John G Gillen, S V. Roberson, C M. Ng, M Stranick
Abstract: Secondary ion mass spectrometry (SIMS) is used to image the spatial distribution of elemental and molecular species on the surface and in cross-sections of doped human hair using a magnetic sector SIMS instrument operated as an ion microprobe. Analy ...

292. Fractal Dimension of Particle Outlines: Meaning, Utility, Limitations, Standard Images and Examples
Topic: Nanotechnology
Published: 4/1/1999
Author: David S. Bright
Abstract: Only a handful of shape parameters, such as aspect ratio and circularity, are in common use for characterizing individual microscopic particles. The fractal dimension, D, is seeing increased use as an additional shape parameter because particle shape ...

296. Standard Test Data for Estimating Peak Parameter Errors in X-Ray Photoelectron Spectroscopy: I. Results for Peak Binding Energies
Topic: Nanotechnology
Published: 10/1/1998
Authors: Joseph M Conny, Cedric John Powell, Lloyd A. Currie
Abstract: Standard test data(STD) are simulations of analytical instrument responses that help determine the veracity of computer-based, data analysis procedures that are typically used with instruments. The STD were developed for determining errors in peak p ...

297. Quantitative secondary ion mass spectrometry imaging of self-assembled monolayer films for electron beam dose mapping in the environmental scanning electron microscope
Topic: Nanotechnology
Published: 7/1/1998
Authors: John G Gillen, Scott A Wight, David S. Bright, T M. Herne
Abstract: Fluorinated alkanethiol self assembled monolayers (SAM) films immobilized on gold substrates have been used as electron-sensitive resists to map quantitatively the spatial distribution of the primary electron beam scattering in an environmental scann ...

298. Atomic Hydrogen for the Formation of Abrupt Sb Doping Profiles in MBE-Grown Si
Topic: Nanotechnology
Published: 5/1/1998
Authors: P E Thompson, C Silvestre, M E Twigg, G Jernigan, David S Simons
Abstract: Previously atomic hydrogen has been shown to be effective in reducing the segregation of Ge on Si[100] during solid source molecular beam epitaxygrowth. In this work we have investigated atomic hydrogen to determine if it is equally effective in red ...
