Abstract

A photosensitive device that includes a conductive electrode, a dielectric layer, a sensing electrode composed of a two-dimensional layered material, and a photoactive layer which can be configured to absorb electromagnetic radiation. The photosensitive device also includes a single-ended measurement electrode for determining the electric potential of the sensing electrode.
