Abstract: A high voltage pulse generated by changing the temperature of a pyroelectric crystal was used to induce strong electron emissions from a ferroelectric cathode. The effects of the extracting voltage provided by an external power source or by another pyroelectric crystal on the electron emission property were investigated. Similar as for normal ferroelectric cathode, both the electron emission current and the total emitted electrons were found to increase with the increasing extracting voltage. However, the fina…
