摘要 研究了纳米石墨晶的场发射特性。介绍了纳米石墨晶薄膜的制备方法,通过扫描电镜和Raman光谱对纳米石墨晶的结构进行了分析。场发射特性测试表明纳米石墨晶薄膜的场发射阈值电场为1.8V/μm。根据实验结果计算出纳米石墨晶的有效功函数在0.75～1.62eV之间。研究表明纳米石墨晶薄膜具有一些独到的特点,也非常适合场发射显示用冷阴极的制备。 Field emission performances of graphite nanocrystalline film are researched in this paper. The graphite nanocrystalline film is synthesized by hot filament CVD method in mixture gas of hydrogen and methane. The structure of graphite nanocrystalline film is studied by SEM and Raman spectra. Field emission measurement of graphite nanocrystalline shows it has threshold electric field of 1.8V/μm, and has better effective work function between 0.75～1.62eV. Research results show that graphite nanocrystalline film is suitable for application to field emission display device.
