Ferroelectric Cathode

Electron emission from ferroelectric cathodes is commonly suggested as an electron source for different application due to its special characteristics such as high current density, easy treatment and operation, etc. The technology of (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PMN-PT) ferroelectric cathode is introduced in this paper. Stable emission current is obtained from the PMN-PT ferroelectric cathode and the characteristic of ferroelectric electron emission is deal with as well.

Ferroelectric Cathode

The technology of (Pb,La)(Zr,Ti)O3(PLZT) ferroelectric cathode is introduced. Stable emission current and high current density are obtained from it driven by positive high-voltage pulses with a repetition rate of 80 Hz. Proximity-imaging techniques are used to record the electron beam spot shape.
