采用化学气相沉积工艺设计了一种新型的陶瓷场发射极。用于构成发射体的材料有两个主要特征：尖端非常尖锐的导电Al：ZnO晶须和尖端具有相对较低电子亲和力的非晶态碳和相关涂层材料。合成了一些晶须聚集体，作为晶须尖端曲率半径的函数。此外，本实验还提供了四种非晶态涂层：C：H、具有C-H和N-H端面的CNX：H、具有N-H端面的CNX：H和CNX薄膜。场发射性能不仅受尖端曲率半径的影响，还受非晶态碳及其相关薄膜的端面结构的影响。
A new type of ceramic field emitter was designed using the chemical vapor deposition process. There are two major features of the materials used to construct the emitter: an electrically conductive Al:ZnO whisker with an extremely sharp tip and amorphous carbon and related coating materials with a relatively low electron affinity at the tip region. Some aggregations of whiskers were synthesized as a function of the radius of curvature at the whisker tip. In addition, four types of amorphous coatings were provided for this experiment: C:H, CNx:H with C–H and N–H terminations, CNx:H with N–H termination and CNx films. The field emission property was influenced not only by the radius of curvature at the tip but also by the termination structure of the amorphous carbon and related films.
