Paper Abstract

The new types of slow surface polaritons are demonstrated to propagate at the interface of homogeneous semifinite space and the layer-periodical structure (classic superlattice), which is made with layers of semiconductor and dieletric. For modern semiconductor and dielectric materials the phase velocity of this waves is value of order Vph approximately equals 4 X 107 sm/s under the real parameters. Velocity of the carrier drift is known to be less than 7 X 107 sm/s. It is shown in this paper, that slow surface polaritons can interact efficiently with carriers moving in homogeneous space. Different types of instability are analyzed analytically and numerically. Increments of instability are obtained.
