Hot Electrons and Integrated Photonics for Electron Emitters

Rehan Kapadia, University of Southern California

In this talk, we will discuss some of our recent work on how hot electronics and integrated photonics can be used to fabricate electron emitters. First, we show how hot-electron processes can dramatically reduce the optical power densities required for photoemission. Then, we discuss how integrated photonics can be used to create photocathodes exhibiting simultaneous high quantum efficiency, low mean transverse energy, and fast temporal response critical for next generation electron sources.
