A Magnetopolaron in a Quantum Well in Arbitrary Magnetic Field Strength at a Finite Temperature |
| |
| Abstract: | Taking into account the interaction of an electron with both bulk longitudinal-optical and surface longitudinal-optical phonons, we study the temperature dependence of the properties of a magnetopolaron in a quantum well in arbitrary magnetic field strength at a finite temperature. It is indicated that the temperature dependence of the self-trapping energies of the magnetopolaron is tremendously related to the strength of the magnetic field. The results also show that the electron-surface LO phonon interaction as well as the electron-bulk LO phonon interaction play important roles, especially when the quantum well width is getting thinner. |
