Abstract
We have investigated the electronic structure of the p-type diluted magnetic semiconductor by photoemission spectroscopy. The Mn partial density of states is found to be basically similar to that of However, the impurity-band-like states near the top of the valence band have not been observed by angle-resolved photoemission spectroscopy unlike This difference would explain the difference in transport, magnetic and optical properties of and The different electronic structures are attributed to the weaker Mn hybridization in than in
