Abstract

Synchrotron radiation soft x-ray photoemission spectroscopy was used to investigate the native oxide of n-type single-crystal CuInSe₂. Photoemission measurements were acquired on the oxide surface before and after removal using sputter etching. Observed changes in the valence-band electronic structure as well as changes in the In 4d and Se 3d core lines were correlated with the interface chemistry at the oxide/CuInSe₂ interface. These results show the native oxide to be composed of an In₂O₃ outer layer (no SeO₂) with an additional Cu₂Se interface layer.
