ABSTRACT:
Metal alkoxycarboxylate-based liquid precursor solutions are used to form electronic devices (100) that include mixed layered superlattice materials (112) of a type having discrete oxygen octahedral layers (124) and (128) collated with a superlattice-generator layer (116). The precursor solutions include a plurality of metal moieties in effective amounts for yielding the layered superlattice materials. These metal moieties are mixed to include an A/B portion capable of forming an A/B layer (124), a perovskite-like AB layer portion capable of forming a perovskite-like AB octahedral layer (128), and a superlattice-generator portion capable of forming the superlattice-generator layer (116). The precursors are deposited in liquid form upon a substrate and annealed to provide the layered superlattice materials.
