利用KrF准分子激光器及聚酰亚胺靶在硅衬底上沉积出了类石墨薄膜。借助于X射线光电子谱及Raman光谱手段对薄膜微结构进行了分析。并用该薄膜作阴极，研究了其场发射特性。实验结果显示出该薄膜具有较好的场电子发射性能，发射点密度高达1×105/cm2以上。有可能作为一种新型的冷阴极电子源。

The graphite-like film was prepared by pulsed laser deposition technique (PLD) using a KrF excimer laser (λ=248 nm). The structure of the film was investigated using X-ray Photo-electron Spectroscopy (XPS) and Raman spectroscopy, it indicates that graphite structure existes in this film. The mechanism of the field emission from the film was discussed. The emission site density of the film more than 1×105/cm2 was obtained. The experimental results indicate that the graphite-like film could be a new type of a cold cathode electronic source for use.
