Oscillations of nonlinear characteristics of samples with small dimensions
Orlov A. O., Savchenko A. K.
The detection of a low-frequency signal and the generation of a second-harmonic signal have been observed in the channel of a GaAs field-effect transistor with dimensions of 2 X 200μπι. This second-harmonic signal oscillates as a function of (a) the number of electrons in the channel and (b) the magnetic field.
