Designing Plasmonic Hot Carrier Devices for Uncooled Infrared Photodetection

Surface plasmon resonance transduces photons into energetically “hot” electrons, which provides new Schottky-based platforms for infrared photodetectors without need for cooling infrastructure. Material design principles towards a multiphysics computation tool are presented where performance is governed by plasmonic activity, density-of-states, and the Schottky barrier.
