Holes' character and bond versus charge disproportionation in $s-p$ $AB{X}_3$ perovskites

Mohammad Reza Benam, Kateryna Foyevtsova, Arash Khazraie +2

We use density functional theory methods to study the electronic structures of a series of $s-p$ cubic perovskites $AB{X}_3$: the experimentally available SrBiO${}_3$, BaBiO${}_3$,…
