Abstract

The valence-band and conduction-band electronic structure of pyrite-typeCoSe2has been investigated by means of ultraviolet-photoemission, synchrotron-radiation-photoemission and inverse-photoemission spectroscopies. The fully occupied Co 3d states witht2gsymmetry are observed as a main peak at -1.0 eV relative to the Fermi level(EF), and the partially filled Co 3d states withegsymmetry are observed as a shoulder at theEFside of the main peak. On the other hand, the structure due to the unoccupied Coegstates appears at 0.6 eV in the inverse-photoemission spectrum. The electronic structure ofCoSe2is similar to that ofCoS2. The electron correlation is more important forCoSe2than forCoS2.
