Abstract
The electronic structures of perovskite-type metavanadates SrVO 3 and NaVO 3 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 SrVO 3 can be considered as a simple metal. Additionally, it is pointed out that a rigid band picture is still valid for these metavanadates.
