Taking into account the interactions of both bulk longitudinal optical (LO) phonons and surface optical (SO) phonons and using Haga's perturbation method, we derive an effectiveHamiltonian for the interface wagnetopolaron in polar crystals at zero temperature. We illustrate in details how to solve this effective Hamiltonian analytically and we obtain explicit formulae not only for the electron cyclotron mass associated with the Landau levels but also for the self-trapping energy of the magnetopolaron with respect to its first three quantum states in the direction normal to the interface of the system. Numerical results are calculated for some 11-V1 and III-V semiconductor compounds, indicating that the bulk LO phonons and SO phonons do have different trends of effects on the electron in different quantum states.

“…[14]- [20]), yet rather insufficient attention has been paid to surface and interface magnetopolarons in semi-infinite crystals. Until recently, one of the authors (Shi-Wei GU) and his collaborators' 21 ' have made some detailed investigations on the properties of the interface magnetopolarons with generalized Larsen's method' 13 ' in the zero temperature case and subsequent extension to the finite temperature case has also been made' 22 " 24 '.…”

Taking into account the interaction of an electron with both, bulk longitudinal-optical (BO) and surface-optical (SO) phonons, the cyclotron resonance of a magnetopolaron in a polar-crystal slab at finite temperatures is investigated by using the generalized Larsen perturbation-theory method. The temperature dependence is studied of the cyclotron resonance mass of a magnetopolaron in the resonant region of the GaAs slab.Es wird die Zyklotronresonanz eines Magnetopolarones in einer polaren Kristall-Schicht, wobei sowohl Elektron-longitudinal-optisches (B0)-Phonon-als auch Elektron-optisches Oberflachen (SO) Phonon-Wechselwirkungen beriicksichtigt werden, mit der verallgemeinerten Larsen-Methode bei endlichen Temperaturen untersucht. Die Temperaturabhangigkeit der Zyklotronresonanzmasse dieses Magnetopolarons im GaAs-Film im Resonanzgebiet wird diskutiert.
