Report on the CCPR-S2 Supplementary Comparison of Area Measurements of Apertures of Radiometry

February 7, 2003

Author(s)

Maritoni A. Litorja, J B. Fowler

The accuracy of aperture area measurements is vital to many radiometric and photometric measurements. The Consultative Committee on Photometry and Radiometry (CCPR) undertook an international comparison of the methods by which member laboratories measure

Geometric Area Measurements of Circular Apertures for Radiometry at NIST

February 1, 2003

Author(s)

J B. Fowler, Maritoni A. Litorja

NIST has established a geometric aperture-area measurement facility for circular apertures. The instrument consists of an interferometrically controlled XY translation stage for high-accuracy positioning and a video microscope for detection fo the aperture

Oxygen Atom Interactions with Fused Silica Surfaces: 1 and u3 P State-Resolved Energy Transfer Dynamics

January 1, 2003

Author(s)

Steven A. Buntin, Maritoni A. Litorja

A laser-based O atom beam source together with state-resolved detection techniques are used to characterize the energy transfer dynamics of ground ( 3PJ) and electronically-excited ( 1 ) state O atoms interacting with a fused silica surface. Time-of-flight

Oxidation of Deuterium-, Acetylene-, and Ethylene-Terminated Si(100) by Atomic Oxygen

January 1, 2002

Author(s)

Maritoni Litorja, Steven A. Buntin

The oxidation of deuterium-, ethylene- and acetylene-terminated Si(100) by gas-phase atomic oxygen is evaluated using Auger electron spectroscopy. The atomic oxygen is generated by the 157 nm laser photolysis of O 2, which results in nominally a 50/50 mix

Oxidation of Ethylene and Acetylene Adsorbed on Si(100) by Atomic Oxygen

January 1, 2001

Author(s)

Maritoni A. Litorja

The oxidation of Si(100) covered with deuterium, ethylene and acetylene by oxygen atoms was studied using Auger electron spectroscopy. Oxygen atoms were generated by vacuum ultraviolet (157 nm) laser photolysis of molecular oxygen. The oxygen uptake is
