Energy loss of charged particle on the waves excitation in semiconductor cylinder with two-dimensional electron gas on the side surface

One of the urgent problems of modern radiophysics is the study of the fundamental properties of solid-state structures that contain nanodimension fragments. Studies of the excitation mechanisms of electromagnetic waves when the charged particles move in various electrodynamic systems form the basis of electronics. In this case, a number of the fundamentally important characteristics of structures include their dispersion equations. They allow to determine the place of electrodynamic structures in the radio physical systems of different purposes. An energy loss of a charged particle per unit time on the waves and/or oscillations excitation in the system is the data characteristic. In electrostatic approximation the dispersion equation describing the eigenmodes of semiconductor cylinder with the layer of two-dimensional electron gas on the side surface (3D+2D-plasma) has been obtained. The energy loss of charged particle was found when it was moving in external magnetic field that has the intensity vector parallel to the symmetry longitudinal axis of the 3D+2D-plasma of cylindrical configuration. It was noted that the obtained relation has the universal character. With the help of it the energy loss may be determined for rotary motion of particle around the cylinder and its translational motion parallel to the cylinder generatrix. The effect of non-reciprocity of the eigenmodes excitation of 3D+2D plasma cylinder was discovered. These modes have identical structures of the field distribution, but differ in the propagation direction along the azimuthal coordinate. Research results extend our conceptions about the electrodynamic properties of systems with plasma mediums and systematize the knowledge of the excitation mechanisms of electromagnetic waves in electrodynamic systems that form the basis of microwave devices.
