CHARACTERIZING ELECTRON EMISSION FOR NANOEMITTER ARRAYS USING THEORY AND MOLECULAR LEVEL SIMULATIONS
Abstract
Characterizing and predicting electron emission mechanisms and behavior is vital for ensuring that electrical devices avoid limiting or damaging operating conditions for multiple applications relevant to the United States Air Force, including high power microwaves, electric thrusters, timeresolved electron microscopy, nano vacuum transistors, thermionic energy converters, and directed energy. Recent theoretical developments include deriving analytic solutions for space-charge limited current (SCLC) for non-planar diodes and using matched asymptotic analyses to determine when simple equations for electron emission mechanisms may be used instead of complicated solutions coupling multiple mechanisms.
