The electronic structure of BaPbO3 in the cubic (a) and tetragonal phases
(c). The corresponding surface states in a [001] slab are presented in Figs. 5(a, b) in blue color. (b) shows the calculations for a superstructure of Ba2PbBiO6, which qualitatively displays the substitution effect of Bi with Pb in the random alloy BaPbxBi1-xO3.
