| Abstract: | The ferroelectric material is a novel cathode material, which is characterized by its low vacuum requirement, convenient fabrication, low work function and fast reactive rate. In this paper, the principles of ferroelectric cathode are discussed and the emission experiments of several primary ferroelectric cathode materials are reviewed, including low voltage ferroelectrie emission experiment. In addition, the application of the ferroelectric cathode material as well as its prospect is also discussed. |
