11. Fermi Level Alignment in Self-Assembled Molecular Layers: The Effect of Coupling Chemistry
Published: 8/1/2006
Authors: Christopher D Zangmeister, Steven W Robey, Roger D van Zee
Abstract: Photoelectron spectroscopy was used to explore changes in Fermi level alignment, within the p-p* gap, arising from changes in the coupling chemistry of conjugated phenylene ethynlene oligomers to the Au surface. Self-assembled monolayers were formed ...

12. Fermi Level Alignment and Electronic Levels in Molecular Wire Self-Assembled Monolayers on Au
Published: 10/1/2004
Authors: Christopher D Zangmeister, Steven W Robey, Roger D van Zee, Yuxing Yao, J M Tour
Abstract: A combination of one- and two-photon photoelectron spectroscopies are used to determine the electronic structure around the Fermi level for self-assembled monolayers of a prototypical molecular wire , 4,4 -(ethynylphenyl)-1-benzenethiol (C6H5-CͰ ...

13. Valence Electron Orbitals of an Oligo(p-phenylene-ethynylene)thiol on Gold
Published: 3/1/2004
Authors: Christopher D Zangmeister, Steven W Robey, Roger D van Zee, Yuxing Yao, J M Tour
Abstract: 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 th ...

14. Initial Etching of GaAs (001) During H^d2^ Plasma Cleaning
Published: 9/1/2000
Authors: Steven W Robey, K Sinniah
Abstract: The initial etching of GaAs(001) during remote H^d2^ plasma etching for oxide removal was examined using Atomic Force Microscopy (AFM), coupled with in situ Reflection High Energy Diffraction (RHEED) and Auger spectroscopy. Localized etching of the ...

15. Mg/GaAs(001): A Highly Anisotropic Reaction Morphology
Published: 12/31/1999
Author: Steven W Robey
Abstract: The spontaneous growth of one-dimensional structures during reaction of Mg on GaAs(001) 4x2 Ga-stabilized surface was observed by in situ electron diffraction and ex situ atomic force microscopy (AFM). Reaction led to growth of an epitaxial, cubic p ...

16. Anisotropic Microstructure Development During the Reaction of Mg With GaAs
Published: 2/18/1998
Author: Steven W Robey
Abstract: Reaction of Mg with GaAs (001) surface occurs at substrate temperatures above 250 K and leads to 3D growth of an epitaxial, cubic reaction phase with a lattice constant of 0.62 + 0.02nm, 9% larger than GaAs. The resulting anistotropic, 3-demiensiona ...

17. Interfacial Reaction Effects in the Growth of MgO on GaAs(001) by Reactive MBE
Published: 2/18/1998
Author: Steven W Robey
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=901805

18. Composition Dependent Electronic Structure Effects in Nd^d1^-xSr^dx^TiO^d3^
Published: 12/1/1997
Authors: Steven W Robey, V E Henrich, C Eylem, B W Eichhorn
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=100371

19. Photoelectron Spectroscopy Studies of Cr(001) Near-Surface and Surface Magnetism
Published: 2/1/1986
Authors: L Klebanoff, Steven W Robey, Guangyao Liu, D Shirley
Abstract: Angle-resolved photoelectron spectroscopy (ARPES) studies of Cr(001) near-surface and surface electronic structure are reviewed. The near-surface energy band dispersions were investigated along the [010] direction parallel to the crystal surface. T ...

20. Comparison of Gas-Phase and Chemisorbed Photoemission Spectra of Oligo(para-phenylene-ethynlene)s
Published: Date unknown
Authors: Steven W Robey, Roger D van Zee, Christopher D Zangmeister, N E Gruhn, Yuxing Yao, J M Tour
Abstract: Ultraviolet photoemission spectra of the three-ring oligo(para-phenylene-ethynylene) and corresponding thiol were measured in the gas phase and compared to the spectrum of the thiolate chemisorbed on gold. The gas-phase spectra were simulated with va ...
