Abstract
A pixel including a substrate and a plurality of photoconductive layers sequentially deposited on and substantially parallel to the substrate and configured to receive incident electromagnetic radiation. Each photoconductive layer is configured to absorb a different wavelength range of the incident electromagnetic radiation and configured to provide an indication of an amount of incident electromagnetic radiation within the corresponding wavelength range absorbed by the layer based on a change in the conductance of the layer.
