Abstract

The electron emission characteristics of PLZT 8/65/35 ferroelectric are studied. High current density has been obtained from PLZT 8/65/35 ferroelectric cathode. The source of the disturbance in the experiment is discussed and several methods to reduce the disturbance are proposed. It is discovered that there is a voltage threshold, and the electron emission will not occur until the amplitude of the pulse exceeds the threshold. Moreover, there are two current peaks in the FE electron emission curves, the primary peak remains stable in location and intensity, while the secondary one shows instability during repeating experiments.
