Abstract :
The nonlinear interaction of space charge waves including amplification and conversion to high frequencies in n-GaN semiconductor films, possessing the negative differential conductance phenomenon, is presented. The simulation results suggest amplification and frequency multiplication for input signals with frequencies f <; 220 GHz using the balance equations model.
