Abstract

Pyroelectrically induced electron emission from different ferroelectric single crystals and ceramics is studied. Ii is observed that (Pb,La)(Zr,Ti)O₃ ceramics generate rather low ferroelectric electron emission (FEE) current compaed with single crystals such as triglycine sulphate and lithium niobate. Figures of merit for FEE cathodes in the pyroelectric excitation mode are derived. It is shown that a physical origin and consequently figures of merit are quite different for FEE cathodes and conventional field electron cathodes. @ 1995 American Institute of Physics.
