1. An electron emitter comprising:
- an emitter section made of a dielectric material;
a first electrode formed in contact with said emitter section;
a second electrode formed in contact with said emitter section;
a slit formed between said first electrode and said second electrode;
a charging film formed at least on a surface of said second electrode; and
means for inducing emission of electrons by polarization inversion from at least a portion of said emitter section which is exposed through said slit.

Abstract
An electron emitter has an emitter section formed on a substrate, and a cathode electrode and an anode electrode formed on a same surface of the emitter section. A slit is formed between the cathode electrode and the anode electrode. A drive voltage from a pulse generation source is applied between the anode electrode and the cathode electrode. The anode electrode is connected to the ground. A charging film is formed on a surface of the anode electrode.
