Plasma oscillations of the two-dimensional electron gas in the field-effect transistor with a cylindrical gate electrode

Abstract

The frequency characteristics of the two-dimensional electron gas in the field-effect transistor with with a cylindrical gate electrode are obtained in the framework of the linear hydrodynamic model. The effect of the transverse dimension and the position of the gate electrode and the parameters of thetwo-dimensional electron gas layer on the resonance characteristics of the field-effect transistor is analyzed. The practical prospects of the results in the development of nanosized oscillators and detectors of the terahertz electromagnetic radiation are outlined.
