Electron photodetector with high detection rate and fast response speed

Light can excite plasmons on the metal surface, and the plasmons can further excite high-energy hot electrons. These hot electrons can cross the metal/semiconductor Schottky junction to form a current, thereby realizing the conversion of light to electricity and realizing optoelectronics.
