Abstract

The propagation of surface electromagnetic waves along a uniform magnetic field is studied in a quantum electron-hole semiconductor plasma. A forward propagating mode is found by including the effect of quantum tunneling. In the classical limit (ℏ→0), one of the low-frequency modes found is similar to an experimentally observed one in n-type InSb at room temperature. The surface modes are shown to be significantly modified in the case of high-conductivity semiconductor plasmas where electrons and holes may be degenerate. The effects of the external magnetic field and the quantum tunneling on the surface wave modes are discussed.

      18. At room temperatures, the conductivity of intrinsic semiconductors in which electron and hole densities are equal may be relatively low. However, this can be enhanced by adding some impurities (doping) in the background plasma. Furthermore, in the case of n-type (extrinsic) semiconductors, which were also used in the experiment of Ref. [1] as a sample, the electrons are considered to be major carriers.
