Electron emitter, drive circuit of electron emitter and method of driving electron emitter

摘要

An electron emitter has an electric field receiving member formed on a substrate, a drive electrode formed on one surface of the electric field receiving member, and a common electrode formed on the one surface of the electric field receiving member, with a slit defined between the drive electrode and the common electrode. The drive electrode is supplied with a drive signal from a pulse generation source, and the common electrode is connected to a common potential generation source (GND in the illustrated embodiment). The slit has a width d in the range from 0.1 mum to 50 mum.
