Topological (Sliced) Doping of a 3D Peierls System: Predicted Structure of Doped BaBiO3

Ilka B. Bischofs, Philip B. Allen, Vladimir N. Kostur +1

At hole concentrations below x=0.4, Ba_(1-x)K_xBiO_3 is non-metallic. At x=0, pure BaBiO3 is a Peierls insulator. Very dilute holes create bipolaronic point defects in the Peierls…
