Repeatable electron emission from (Pb,La)(Zr,Ti)O3 ferroelectric cathodes using direct-current reset

The use of ferroelectric (Pb,La)(Zr,Ti)O3 as a cathode material is investigated. It has been suggested in the literature that by rapidly changing or reversing the spontaneous polarization in the ferroelectric, a large charge imbalance can be produced at the surface of the material. The field from th...
