To find a proper and convenient way in electron emitter research , in the paper , we have discussed the essential and possibility of setting up a new pld ( pulsed laser deposition ) device which connects with aes ( auger energy spectra ) , and built such device in order to complete cathode deposition and analysis without exposing to the atmosphere and carried out cathode in - situ preparation and analysis electron emission phenomenon is a physical process taken place in surface of electron emitter 为了解决电子发射体(阴极)研究方法中存在的问题，并寻求一种适当的、方便的阴极研究实验方法，本论文论证了建立与aes相连的pld装置的必要性和可行性，并实际建立了这一装置，实现了阴极的原位沉积、原位分析。电子发射现象是在电子发射体表面发生的物理过程，发射表面是由活性元素构成的动态平衡系统，这一系统直接决定电子发射性能。表面分析手段对阴极研究是必不可少的。
Since the discovery of cnt ’ s and find that cnts have small diameter and high length diameter ratio and can be look as one - demission material , it can be used as emission emitter of fed . especially , the aligned cnts array can be seen innumerable single cathodes which are lined regularly and form array . so growing aligned cnts array in selective area is the key technology to product cnts fed , which is also the necessary condition of cnts micro - electronics device 自碳纳米管发现以来,由于碳纳米管的直径很小、长径比大,故可视为准一维纳米材料,可作为场发射平板显示的尖端发射体,特别是定向碳纳米管阵列可看成是无数根单尖阴极规则的排列起来形成阵列式,是理想的场发射平板显示器的尖端发射体。
