Electrical and thermal modeling of a gated field emission triode

A rather complete numerical simulation program for electrical and thermal characteristics of a two-dimensional gated field emission triode is presented. Important aspect such as space charge effect, Joule heating, Nottingham effect as well as thermally-dependent heat conductivity and electrical resistivity are included. Computation accuracy and efficiency is established via a automatically adjusted mesh structure. Good matches with published measured data are observed. New insight over triode on-set voltages and thermal stabilized tip structure are suggested.<
