Electronic structure of bapb1-xbixo3

Abstract

The results of linear augmented-plane-wave electronic structure calculations for the perovskite-type compounds BaPb1-xBixO3 are reviewed in the light of recent experimental measurements of the x-dependent electronic properties near isF(A:). In the metallic regime x<0.35, satisfactory agreement is found between the calculated density of states N(Ep, x) and specific-heat data. The experimental-theoretical ratio suggests an electron-phonon enhancement factor (1 +λ)=2. A similar comparison between the calculated and observed free-carrier plasma energies Ωp(x) yields - 10% agreement over the entire alloy series. © 1985 The Japan Society of Applied Physics.
