• Squeezing electrons out of 6s2 lone-pairs in perovskite-type oxides 

      Wang, Chun-Hai; Kayser, Paula; Kennedy, Brendan J; Maynard-Casely, H E; Gu, Qinfen; Ling, Chris D
      Published 2019
      Having identified a set of conditions that predispose a solid-state ionic compound to a pressure-induced valence transition, we investigated a series of Bi(III) perovskite oxides. We found such a transition below 10 GPa ...
