Abstract
A hot carrier photodetector has been developed that absorbs approximately 80% of broadband infrared radiation by using a planar nanoscale back metal contact to silicon. Based on the principles of the hot carriers generation in ultrathin metal films, silicon-based CMOS image sensors are developed which operate in the IR diapason. The device uses absorption in an ultrathin metallic nanostructure to generate therein a non-equilibrium electron distribution which subsequently is injected into the silicon material via a Schottky contact at the Si body, thus generating a photoresponse to an incident IR radiation. A pixeled array including interconnected hot carriers metallic nanostructured cell(s) and traditional RGB elements is envisioned to enable RGB-IR imaging from a single silicon based wafer.
