摘要：

Electron emission into vacuum from a thin plate of lead-zirconate-titanate (PZT) ferroelectric ceramics has been observed under the impression of pulse electric field. Electrons are emitted not only from the ceramic surface near the electrode edge but also through the thin metal electrode. The emitted charge per one pulse little depends on pulse frequency when it is less than 2 kHz, and so the current density can be enhanced by increasing the frequency. The emission is observed even at temperatures above Curie temperature. It is considered that the emission is induced by abrupt change of dielectric flux as well as the polarization reversal.
