Abstract:
1. An inorganic electronic device comprising: a nanostructured metal electron source layer comprising a roughened metal surface having surface irregularities in the nm to tens of nm range and a surface plasmon resonance within the visible and near-visible spectrum range; a semiconductor layer in contact with the metal electron source layer, wherein the metal electron source layer and the semiconductor layer form an interface that is a Schottky barrier; and an electrode layer in contact with the semiconductor layer, wherein the electrode layer forms an ohmic contact to the semiconductor layer; wherein the nanostructured metal electron source layer comprises silver; wherein the semiconductor layer comprises TiO wherein the nanostructured silver layer is formed by bombarding a silver target with an ultrafast laser pulse to deposit a thin film of silver nanoparticles onto the layer of TiO
