Abstract

The effects of surface treatments in H₂, N₂, and O₂ on electron emission have been investigated for a ferroelectric electron emitter with a unique porous electrode. The electron emission was markedly enhanced after surface treatment in H₂ at 90 kPa. The electron emission density was about 500 nC/cm², 1.6 times higher than that of a nontreated emitter. On the other hand, electron emission after surface treatment in O₂ at 90 kPa was decreased to about two-third of that of the nontreated emitter. These results indicate that electron emission can be significantly influenced by modification of the ferroelectric surface state.
