Abstract:
1. A device supporting a photoelectrochemical process comprising: a substrate lattice mismatched to a predetermined crystalline wurtzite semiconductor material; at least one semiconductor nanostructure of a plurality of semiconductor nanostructures grown onto the surface of the substrate without a patterned buffer layer, each semiconductor nanostructure comprising a first predetermined portion disposed at the substrate surface which is the predetermined crystalline wurtzite semiconductor material composed of a predetermined group III element and a predetermined group V element; and at least one core-shell nanostructure of a plurality of core-shell nanostructures disposed on the exterior surface of the at least one semiconductor nanostructure of a plurality of semiconductor nanostructures, each core-shell nanostructure upon the exterior surface comprising a core formed from a first predetermined material and a shell formed from a second predetermined material and acting as a co-catalyst for the photoelectrochemical process, wherein the photoelectrochemical process occurs directly at the surfaces of the nanostructure coated semiconductor nanostructure absent any other input other than light within a predetermined wavelength range established in dependence upon the predetermined crystalline wurtzite semiconductor material.
