Raman scattering study of the thermal oxidation of InP

Abstract
Reflection Raman scattering has been used to study thermally grown air‐oxidized films on InP. Elemental red phosphorus is detected in films grown between 350 and 550 °C. At oxidation temperatures exceeding 550 °C, InPO4 is observed with some In2O3 also present as a minor film constituent.
