Buffer layer for the crystal growth of metal oxides of perovskite type in particular on amorphous substrates

Abstract

A multilayer conductive system of metal oxides, the system including a substrate; a layer of a crystalline binary metal oxide deposited on the substrate, and a layer of a crystalline conductive metal oxide having a crystalline structure of perovskite type superposed over the layer of binary metal oxide, where the binary metal oxide of the layer has a local lattice mismatch of less than 5% with respect to that of the metal oxide of the layer, provided that when the metal oxide of perovskite type of the layer is a crystalline transparent conductive metal oxide, the substrate is transparent, and the thickness of the crystalline binary metal oxide layer is <20 nm, preferably <10 nm, most preferentially 5-7 nm.
