摘要：
A photodetector has a two dimensional conductive channel and a quantum dot layer configured to generate charge on exposure to incident electromagnetic radiation. The surface texture of the quantum dot layer has texturing to provide surface roughness which increases the amount of electromagnetic radiation absorbed in the quantum dot layer in comparison to a photodetector having a flat (non-textured) incident electromagnetic radiation surface.
