Abstract

The electronic structure of Cr_1-δTe (δ=0.05, 0.25, 0.375) has been studied by photoemission spectroscopy. Structures near the Fermi level are qualitatively explained by the density of states (DOS) given by band-structure calculations, butsignificant discrepancies exist in the higher binding energy region. Configuration-interaction cluster-model calculationshave been performed and the overall experimental features have been explained, indicating significant electron correlation effects in these compounds.
