Bond versus charge disproportionation in the bismuth perovskites
Arash Khazraie, Kateryna Foyevtsova, Ilya Elfimov +1
We develop a theory describing a parameter based phase diagram to be associated with materials incorporating skipped valence ions\cite{Varma}. We use a recently developed tight-bin…
Oxygen holes and hybridization in the bismuthates
Arash Khazraie, Kateryna Foyevtsova, Ilya Elfimov +1
Motivated by the recently renewed interest in the superconducting bismuth perovskites, we investigate the electronic structure of the parent compounds ABiO (A= Sr, Ba) using…
Hybridization effects and bond-disproportionation in the bismuth perovskites
Kateryna Foyevtsova, Arash Khazraie, Ilya Elfimov +1
We propose a microscopic description of the bond-disproportionated insulating state in the bismuth perovskites BiO (=Ba, Sr) that recognizes the bismuth-oxygen hybridizat…
