The ferroelectric cathode

The ferroelectric electron cathode is a newly developed source of electrons. The mechanism of electron emission from the ferroelectric ceramic to the vacuum is different than that of the common thermionic cathode. As a result, its useful features enable new schemes of microwave tubes with considerable advantages such as a high current electron beam. What's more, the restrictions associated with its limitations may coincide with specific needs of various new microwave generators such as a disposal microwave tube.
