Abstract:
A photodetector ( 400 ) has a two dimensional conductive channel ( 302, 408 ) with source and drain electrodes ( 404 ) configured to enable a flow of electrical current through the two dimensional conductive channel ( 302, 408 ); and a quantum dot layer ( 304, 406 ) overlying the two dimensional conductive channel ( 302, 408 ), the quantum dot layer ( 304, 406 ) configured to generate charge on exposure to incident electromagnetic radiation ( 310 ), the generated charge producing an electric field which causes a change in electrical current passing through the underlying two dimensional conductive channel ( 302, 408 ), the change in electrical current being indicative of one or more of the presence and magnitude of the incident electromagnetic radiation ( 310 ); wherein the quantum dot layer ( 304, 406 ) is configured to have an incident electromagnetic radiation surface ( 312 ) which has a texturing comprising undulations in the surface to provide a surface roughness with an average peak amplitude ( 308 ) of the order of between 10 nm and 300 nm. The surface texture increases the amount of electromagnetic radiation absorbed in the quantum dot layer ( 304, 406 ) in comparison to a photodetector having a flat (non-textured) incident electromagnetic radiation surface.

Claim (Index 20):
The apparatus of  claim 16 , wherein the surface roughness is provided by one or more of:\n the quantum dot layer having a variable thickness providing the surface roughness with an average peak amplitude of the order of between 10 nm and 300 nm; and the underlying surface texture provided to the conductive channel providing the surface roughness with an average peak amplitude of the order of between 10 nm and 300 nm.
