Abstract
UV-ozone oxidation of GaAs epitaxial layers was evaluated for GaAs mol ecular beam epitaxy regrowth. Auger electron spectroscopy was used to determine the conditions leading to a contaminant-free surface before epitaxy; oxide uniformity, surface roughness and crystalline defects w ere also studied using transmission electron microscopy. Finally, the capability of this technique was demonstrated by growing a GaAlAs-GaAs -GaAlAs quantum well on a processed GaAs epitaxial layer.
