Theory of Non-linear Plasma Waves in FETs
Abstract
This report describes the results of the investigation of nonlinear effects in the plasma oscillations in bounded electron systems. We studied an evolution of electron density distribution in the conduction channel of a Field Effect Transistor under various boundary conditions. The decay law of shock like waves in dynamically closed systems was found. We investigated the effects of plasma waves in the nonlinear response of the conduction channel in FET structure. The dependencies of the detector responsivity on the excitation level for different gate length, and electron mobilities was computed. We also studied the change of the wave form in the system with time independent boundary conditions when a small nonlinear dispersion term was included.
