Numerical Hydrodynamic Modeling of Non-Linear Plasma Oscillations in the Conduction Channels of FETs and Application to Non-Linear Transformation of Harmonic Signals.

摘要

We find that the nonlinear wave propagation leads to the interesting nonlinear response in the terminal current even though the applied signal is of much lower frequency then the fundamental plasma frequency. Simllar response is found when the frequencies of applied signals are equal but their amplitudes are different or if there is a phase shift between applied signals. This may allow for the expenmental demonstration of the nonlinear plasma response and some novel device applications.
