Abstract:
1. A method of forming nanophotovoltaic devices, comprising providing a silicon wafer having a buried oxide layer separating a thin silicon layer from the bulk of the wafer, depositing a first metallic layer on an exposed surface of said thin silicon layer so as to form a schottky barrier junction with said silicon surface, removing the oxide layer and the bulk portion of the wafer to generate a structure comprising said thin silicon layer and said metallic layer disposed on a surface thereof, depositing a second metallic layer on an exposed surface of said thin silicon layer opposed to said first metallic layer to form an ohmic contact therewith, applying a photoresist to one of said metallic layers, holographically patterning said resist to generate a two-dimensional holographic recording therein, developing said patterned photoresist to generate a pattern of exposed and unexposed portions, and etching away the exposed portions to generate a plurality of nanophotovoltaic devices.
