Abstract :
Scandate cathode is the most promising cathode type which can be utilized in THz devices. There is a wide transition region in the I-V characteristics of scandate cathode. The low slope and dual slope in the I-V characteristics according with Child-Langmuir law will be discussed in this paper.
