摘要:
Thin‐film electron emitters are described, which operate below 200°K and below a limiting critical applied voltage (&ngr;c) in a stable temperature‐independent regime. Current‐voltage characteristics and normal electron energy distributions are presented. Fabrication and operation criteria are outlined. Comparison with temperature‐dependent emitters is made, and possible conduction mechanisms discussed briefly.
