摘要
Taking into account the interaction of an electron with both bulk longitudinaloptical (LO) and interfaceoptical(IO) phonons, we investigate the magnetic field and temperature dependence of the properties of a magnetopolaron at the interface of polarpolar crystals in an external magnetic field by using the generalized Haga perturbation method. The results reveal that as the magnetic field B is lower than critical strengths BCL and BCI, the selftrapping of the interface magnetopolaron weakens with increasing temperature, but it strengthens with the rising temperature when B is higher than BCL and BCI. The effect of temperature becomes striking while B is close to BCL or BCI. The results also show that the farther from the interface the electron, the more markedly the electronLO phonon interction changes with the variation of temperature. On the other hand, the nearer from the interface the electron, the more distinctly the electronIO phonon interaction changes with varying temperature.
