文摘

An electron emitter based on porous silicon having the strong application potential was prepared in the studying. A new simple and convenient post-treat technique was proposed to improve the electron emission properties of the PS emitter. It demonstrated that the improving of the PS morphology and the oxygen distribution is very important to the PS emitter.
