描述了一种工作在200K和极限临界外加电压(νc)以下的薄膜电子发射器,它工作在与温度无关的稳定区域。给出了电流-电压特性和正态电子能量分布。概述了制造和操作标准。与温度相关的发射体进行了比较,并简要讨论了可能的导电机制。
Thin‐film electron emitters are described, which operate below 200°K and below a limiting critical applied voltage (νc) 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.
