Abstract

It is shown that structuring the top layers of a resonant cavity Schottky photodetector in a way that allows coupling between the wave-vector of incident radiation and that of electron-collective oscillations (plasmons) at the surface of the metallic electrode leads to practically zero reflectance in the case of front illuminated devices. This is expected to result in a consequential enhancement in the quantum efficiency in these photodetectors.
