A Unique Institution: The History of NBS, 1950-1969

June 30, 1999

Author(s)

E Passaglia, K A. Beal

A follow-on to Measures for Progress by Rexmond C. Cochrane, this work covers the history of the National Bureau of Standards (NBS) from 1950-1969. While the book focuses on technical work, the management and administration of the Bureau are also discussed

Development of a Triplasmatron Ion Source for the Generation of SF 5 + and F- Primary Ion Beams on an Ion Microscope Secondary Ion Mass Spectrometry Instrument

May 1, 1999

Author(s)

John G. Gillen, R L. King, F Chmara

A hot filament duoplasmatron ion source operating with argon has been modified by addition of an enclosed expansion cup mounted to the extraction side of the duoplasmatron anode. Using sulfur hexafluoride (SF 6) as a feed gas, this triplasmatron ion source

Elemental and Molecular Imaging of Human Hair Using Secondary Ion Mass Spectrometry

April 1, 1999

Author(s)

John G. Gillen, S V. Roberson, C M. Ng, M Stranick

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. Analysis of

Fractal Dimension of Particle Outlines: Meaning, Utility, Limitations, Standard Images and Examples

April 1, 1999

Author(s)

David S. Bright

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 shapes

Preliminary Evaluation of an SF5+ Polyatomic Primary Ion Beam for Analysis of Organic Thin Films by Secondary Ion Mass Spectrometry

December 1, 1998

Author(s)

John G. Gillen, S V. Roberson

The Formation of Abrupt n+ Doping Profiles Using Atomic Hydrogen and Sb During Si MBE

December 1, 1998

Author(s)

P E. Thompson, C Silvestre, M E. Twigg, G Jernigan, David S. Simons

The Southern California Ozone Study 97 Radiocarbon Experiment

December 1, 1998

Author(s)

George A. Klouda, C. W. Lewis, J L. Marolf, D C. Stiles, K G. Kronmiller, K D. Oliver, J R. Adams

Standard Test Data for Estimating Peak Parameter Errors in X-Ray Photoelectron Spectroscopy: I. Results for Peak Binding Energies

October 1, 1998

Author(s)

Joseph M. Conny, Cedric J. Powell, Lloyd A. Currie

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

Quantitative secondary ion mass spectrometry imaging of self-assembled monolayer films for electron beam dose mapping in the environmental scanning electron microscope

July 1, 1998

Author(s)

John G. Gillen, Scott A. Wight, David S. Bright, T M. Herne

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 scanning

Atomic Hydrogen for the Formation of Abrupt Sb Doping Profiles in MBE-Grown Si

May 1, 1998

Author(s)

P E. Thompson, C Silvestre, M E. Twigg, G Jernigan, David S. Simons

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 reducing
