Abstract

Transparent, electrically conductive vanadium oxide-based perovskite films and methods of making the vanadium oxide-based perovskite films are provided. Transparent conducting vanadate perovskites are made by forming a layer of amorphous vanadate perovskite precursor around a plurality of nanoscale, crystalline, perovskite oxide seeds and heating the layer of amorphous vanadate perovskite precursor at a temperature that favors lateral vanadate perovskite crystal growth from the perovskite oxide seeds over homogeneous crystal nucleation within the layer of amorphous vanadate perovskite precursor material. The crystallization processes can form the desired vanadate perovskite phase directly or via a transformation in a controlled gas environment from an initial crystallized vanadate perovskite phase that has a higher oxidation state.
