Diamond Emission Diodes for High Power Electron Beams

Abstract

This project is to develop a novel device technology to act as a cathode for vacuum-electronic devices. The device operating principle is direct electron emission from a forward biased diamond p-i-n diode. In this device, the combination of high material quality, negative electron affinity, and device geometry allows a large fraction of the current driven through the diode to be emitted directly into the vacuum. This research will be a combined effort by both Arizona State Universityand the JHU Applied Physics Laboratory, with both parties bringing critical expertise to the table.
