Negative and positive thermal expansion-like volume changes due to intermetallic charge transfer based on an ionic crystal model of transition-metal oxides

Materials showing negative thermal expansion (NTE) are technologically important and a few transition-metal oxides with the perovskite structure show large NTE-like volume changes due to intermetallic charge transfer. Here we show that the observed volume changes are primarily caused by the size eff...
