Abstract :
The purpose of this paper is to present theoretical results on current limiting cathode contact InP TED´s in the millimeter wave range. The current limiting effect is obtained from a reverse-biased GaInAsP on InP isotype heterojunction. This kind of cathode contact yields an efficient over length dipolar layers mode up to the ultimate cut-off frequency of the negative differential mobility in InP (~200 GHz). Theoretically expected results are reported. Thermal and frequency limitations are discussed. We also mention the main problems encountered in the preliminary technological study of these devices.
