Abstract

A theory of TM type surface polaritons in semiconductor films possessing depletion transition layer, in which electron concentration changes according to the law of hyperbolic cosine, was built. The influence of dissipative as well as non-dissipative damping, caused by plasma resonance in transition layer, on dispersion properties of normal and tangential modes of surface polaritons was determined. It was shown that in the absence of dissipative damping two dispersion branches both for normal and tangential modes of surface polaritons exist, parted by a frequency gap. Taking into consideration dissipative damping leads to vanishing of the gap and existence of only one dispersion branch both for normal and tangential modes of surface polaritons. The damping of tangential mode therewith exceeds considerably the damping of normal mode.
