Excitation of waves in a semiconductor cylinder with 2D-gas on the side surface by a charged particle moving along the spiral path around the cylinder

Abstract

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 at electrostatic approach. The energy loss of charged particle was found when it moving into external magnetic field that has the strength vector parallel to the symmetry longitudinal axis of the 3D+2D-plasma of cylindrical configuration. The obtained relation allows to find the energy loss in both of a rotary motion of particle around the cylinder and its translational motion parallel to the cylinder generatrix. The effect of non-reciprocity excitation of the eigenmodes 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.
