摘要

The nonlinear interaction of space charge waves including the amplification in microwave range at high electric fields (10–300 kV/cm) in n-GaAs films, possessing the negative differential conductance phenomenon, is presented. Both the amplified signal at the first harmonic of the input signal and the generation of second and third harmonics of the input signal, which are due to the negative differential resistance effect at very high electric fields are shown.
