Monolayers of oligo(phenylene-ethynylene) (OPE) molecules have exhibited promise in molecular electronic test structures. This paper discusses films formed from novel molecules within this class, 2-fluoro-4-phenylethynyl-1-[(4-acetylthio)-phenylethynyl

Valence Electron Orbitals of an Oligo(p-phenylene-ethynylene)thiol on Gold

Christopher D. Zangmeister, Steven W. Robey, Roger D. van Zee, Yuxing Yao, J M. Tour
One- and two-photon photoemission spectra have been measured for monolayers of oligo(para-phenylene-ethynylene) thiolate chemisorbed on gold surfaces. Within 5 eV of the Fermi level, four states are observed, two occupied (2.0 eV and 4.0 eV below the Fermi

This submission is an introduction to Cavity-Enhanced Spectroscopy, a book which is to be published by Academic Press.

Pulsed, Single-Mode Cavity Ringdown Spectroscopy

June 1, 1999
Author(s)
Roger D. van Zee, Joseph T. Hodges, J P. Looney
This paper demonstrates an implementation of single mode cavity ring-down spectroscopy, using a pulse laser system, with near shot-noise limited sensitivity. The rationale for this approach is discussed, the experimental apparatus is described, and the

Measuring Pressures With Cavity Ring-Down Spectroscopy

January 1, 1998
Author(s)
Roger D. van Zee, J P. Looney, Joseph T. Hodges
The industrial demand for sensitive and noninvasive tools with which to measure pressure has spurred the use of optical methods to make these measurements. This paper reviews these industrial needs, and discusses how cavity ring-down spectroscopy can be
