1. A photoconductive device, comprising:
a first electrode configured as a first electrical contact;
a second electrode configured as a second electrical contact; and
a region comprising a doped diamond material positioned between the first electrode and the second electrode, wherein a center of the doped diamond material has a smaller thickness as compared to an edge of the doped diamond material, wherein:
the region comprising the doped diamond material is configured to receive light from a light source operable at a wavelength in a range from 300 nm to 450 nm,
the doped diamond material includes nitrogen as a dopant, and
the first electrode and the second electrode are configured to establish an electric field across the region comprising the doped diamond material such that the region becomes conductive in response to receiving the light from the light source.
