LIGHT EMITTING DIODES, FAST PHOTO-ELECTRON SOURCE AND PHOTODETECTORS WITH SCALED NANOSTRUCTURES AND NANOSCALE METALLIC PHOTONIC CAVITY AND ANTENNA, AND METHOD OF MAKING SAME

摘要

A new ultra-thin high-efficiency photoelectron source utilizing a metallic photonic resonant cavity having a photonic resonant cavity with a top metallic with a plurality of openings, each having an average dimension less than the wavelength of the excitation photons in vacuum, a bottom metallic layer and a photoelectron emission layer of semiconductor positioned between the top metallic layer and the bottom metallic.
