Surface plasmons instability brought about by the flux of charged particles in the media with inhomogeneous potential

摘要

The problem associated with the influence of the potential barrier on the magnitude of the surface plasmon increment (decrement) is discussed. The probability of radiation absorption processes by the energy-quantum electron of the electromagnetic field on the surface of a conducting solid with allowance being made for a finite potential magnitude has been studied. Yet the mechanism of surface oscillation instability has not been studied. The present paper is devoted to solving this problem.
