The field-emission characteristics of cathode arrays based on nanocomposite diamond–graphite film structures with a reinforcing tunnel-thin diamond coating are investigated. These field emission characteristics are not related to the morphology of the emitting surface and cannot be explained in terms of the Fowler–Nordheim model. The effect of the thickness of the diamond coating on the field-emission characteristics and dielectric strength of the cathode heterostructure is determined. The obtained regularities are interpreted based on increasing transparency of potential barriers for electron tunneling due to a decrease in the mirror image forces.

隧道薄膜金刚石薄膜涂覆的场阴极的场电子发射机理

摘要

研究了具有增强型隧道薄金刚石涂层的纳米复合金刚石-石墨膜结构的阴极阵列的场发射特性。这些场发射特性与发射表面的形态无关，因此无法用Fowler-Nordheim模型来解释。确定金刚石涂层的厚度对阴极异质结构的场发射特性和介电强度的影响。基于由于镜像力的减小而增加的用于电子隧穿的势垒的透明度来解释所获得的规律性。
