Electron Doping BaZrO 3 via Topochemical Reduction

We report the topochemical reduction of epitaxial thin films of the cubic perovskite BaZrO. Reduction with calcium hydride yields n-type conductivity in the films, despite the wide bandgap and low electron affinity of the parent material. X-ray diffraction studies show concurrent loss of out-of-plane texture with stronger reducing conditi...More
