摘要: Methods for forming stable, suspended nanomembranes are provided. Also provided are stable, suspended nanomembranes made using the methods and electronic devices that incorporate the stable, suspended nanomembranes as electronically active layers. The methods utilize stiction-aided nanomembrane flattening combined with ultraviolet (UV) radiation-induced adhesion enhancement.

摘要: A method for crystallizing an amorphous multicomponent ionic compound comprises applying an external stimulus to a layer of an amorphous multicomponent ionic compound, the layer in contact with an amorphous surface of a deposition substrate at a first interface and optionally, the layer in contact with a crystalline surface at a second interface, wherein the external stimulus induces an amorphous-to-crystalline phase transformation, thereby crystallizing the layer to provide a crystalline multicomponent ionic compound, wherein the external stimulus and the crystallization are carried out at a temperature below the melting temperature of the amorphous multicomponent ionic compound. If the layer is in contact with the crystalline surface at the second interface, the temperature is further selected to achieve crystallization from the crystalline surface via solid phase epitaxial (SPE) growth without nucleation.

摘要: 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.
