Species-Specific Densities of States of Ga and As in the Chemisorption of Oxygen on GaAs(110).
Pagination or Media Count:
Auger line shape measurements have been made to extract the variation in the local charge distribution around Ga and As sites for chemisorption of oxygen on cleaved and sputter-etched GaAs110. A significant variation with changing O coverage is observed in the Ga spectrum, with a much more subtle change in the As spectrum. Conclusions on the nature of the bonding and on the mechanism for adsorption at both low and high coverages are drawn from these spectra.
