Abstract(in English) | Electron emission into vacuum from a thin plate of ferroelectric lead-zirconate-titanate(PZT)ceramic has been observed under the impression of electric field of pulse consisting of a pair of positve and negative voltages.The emitted charge increases with increasing the positive and the absolute negative voltages of the pulse and the collector voltage.The mimimum absolute value of the negative pulse for electron emission is 40V when the positive voltage is larger than 150V.The maximum peak current density is 70A, cm2.It is considered from the electrode area and thickness dependences of the charge that 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 firquency when it is less than 2kHz,and so the total 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.Cathodoluminescence from phosophers excited by the emitted electronics has been observed. |
