Abstract
The influence of current activation by the breakdown of the electric pulse on changes in the surface morphology and emission characteristics of a field emission (FE) cathode made based on carbon films obtained by deposition in a microwave gas discharge plasma is studied. The current activation of these films is carried out by applying microsecond voltage pulses until an electrical breakdown occurred. It is shown that during the activation, the morphology of the film surface in the breakdown region changes with the formation of a microsized emitting structure, which significantly improves the FE characteristics of the cathodes based on carbon films.
摘要 研究了电脉冲击穿电流活化对基于在微波气体放电等离子体中沉积获得的碳薄膜制成的场发射(FE)阴极的表面形态和发射特性变化的影响。这些薄膜的电流活化是通过施加微秒级电压脉冲进行的,直到发生电击穿。结果表明,在活化过程中,击穿区域的薄膜表面形态发生了变化,形成了微小的发射结构,从而显著改善了基于碳薄膜的阴极的 FE 特性。
