摘要:
A ferroelectric cold cathode comprising a ferroelectric layer formed of a ferroelectric material and provided on its one surface with an emitter which is a projection having a sharp tip portion, a first electrode layer formed on one surface of the ferroelectric layer and having an opening allowing the sharp tip portion of the emitter to be exposed therethrough, and a second electrode layer formed on the other surface of the ferroelectric layer. When a voltage is applied between the first electrode and the second electrode, a dielectric polarization is reversed in the ferroelectric layer, resulting in the emission of electrons from the sharp tip portion of the emitter.
