Charge transfer drives anomalous phase transition in ceria
Ceria has conventionally been thought to have a cubic fluorite structure with stable geometric and electronic properties over a wide temperature range. Here we report a reversible tetragonal (P4(2)/nmc) to cubic (Fm-3m) phase transition in nanosized ceria, which triggers negative thermal expansion i...
