Resumen:
The first stages of oxidation in GaAs(100) have been studied using Auger electron spectroscopy and principal component analysis. We found that at low oxygen exposures (<104 Langmuirs) and in the presence of excited oxygen produced by electron bombardment, GaAs oxidizes via a one-phase process only. This phase involves the simultaneous oxidation of both the elements Ga and As.
