Electron photodetector with high detection rate and fast response speed | #plasmonic thermionic photodetector

Electron photodetector with high detection rate and fast response speed

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.
