ELECTRONIC-STRUCTURE OF SRVO3

The electronic structures of perovskite-type metavanadates SrVO3 and NaVO3 have been investigated by means of the first principles band calculation technique. The electronic states near the Fermi level are mainly contributed from the d-orbitals of the vanadium atom, and the Fermi surface is constructed with four bands. The thermal effective mass is 2.98 m(0), and the calculated electronic structure of SrVO3 can be considered as a simple metal. Additionally, it is pointed out that a rigid band picture is still valid for these metavanadates.
