摘要

制备了两种垂直排列碳纳米管发射体的spindt型阴极阵列。一种方法是从每个微电池的底部直接生长碳纳米管，另一种方法是在spindt型阴极阵列的Mo尖端生长碳纳米管。前者的发射体与多个碳纳米管具有相当好的一致性，而后者则显示可以在微型细胞中形成少量或单个碳纳米管。

Spindt-type cathodes with aligned carbon nanotube emitters

Two kinds of Spindt-type cathode arrays with vertically aligned carbon nanotubes (CNTs) emitters were fabricated. One process involved direct growth of CNTs from the bottom of each micro-cell and the other process was to grow CNTs on Mo tips in Spindt-type cathode arrays. The former had fairly good consistent emitters with a number of CNTs, whereas the latter showed a few or single CNTs in micro-sized cells could be formed.
