Abstract :
We study the negative differential resistance in negative-effective-mass (NEM) semiconductors. The NEM diodes based on the NDR mechanisms have a self-oscillating frequency in the terahertz range. We have investigated the electric domain dynamics in the diodes under dc electric field, and nonlinear dynamics driven by dc+ac voltages.
