The TCPOs are crystallized from their corresponding amorphous films using embedded crystalline perovskite oxide seeds as nucleation sites. The amorphous films have the same complex oxide composition as the TCPO but are in an amorphous form. The crystalline perovskite oxide seeds are themselves formed on a substrate from a thin amorphou[...]
