High angular intensity Schottky electron point source
Abstract:
An electron emitter is produced by applying a work function lowering material that does not require an extensive heating step before the material will function to lower the work function. By eliminating the extensive heating step, a small radius, highly tapered emitter tip will retain its shape to consistently produce a high angular intensity at a reasonable output power level.
