Bludov Y. Surface polaritons in semiconductor superlattices placed into high magnetic fields

Superlattices. To investigate theoretically surface polaritons (SP) in superlattices (SL), formed of two-dimensional systems of charge carriers placed into an external quantizing magnetic field. Dispersion characteristics of SP in infinite type-I and type-II SLs as well as in finite ordered and weakly disordered SLs are investigated. It is found that under an integer quantum Hall effect conditions as external magnetic field varies all characteristics of SP undergo variations in discrete steps. We predicted that when the energy dissipation is taken into account an additional surface polariton appears in the spectrum of SP. Area of application - nanotechnology.
