摘要:
This article suggests an alternative mechanism for electron emission from the ferroelectric ceramic cathode. This mechanism involves the concept of vacuum breakdown initiation from metal‐dielectric cathodes that comprises two stages: the field emission through metal‐ dielectric‐vacuum conjunction followed by the processes resulting in an uncompleted surface discharge. The electron emission thus occurs from the low‐density surface plasma. ©1995 American Institute of Physics.
