Abstract

Valence-band dispersions in Ga1-xMnxAs along the Γ-Δ-X line (k∥[001]) are obtained by angle-resolved photoemission spectroscopy. Compared with the spectra of GaAs, a small energy shift caused by Mn doping is observed for one of the valence bands. In addition, states are observed near the Fermi level in Ga1-xMnxAs. These states show no clear dispersions and behave like an impurity band induced by Mn doping.
