中文摘要 | the effects of lattice vibration on the system in which the electron is weakly coupled with bulk longitudinal optical phonons and strongly coupled with interface optical phonons in an infinite quantum well were studied by using tokuda' linear-combination operator and a modified llp variational method. the expressions for the effective mass of the polaron in a quantum well qw as functions of the well's width and temperature were derived. in particular, the law of the change of the vibration frequency of the polaron changing with well' s width and temperature are obtained. numerical results of the effective mass and the vibration frequency of the polaron for ki/agcl/kl qw show that the vibration frequency and the effective mass of the polaron decrease with increasing well's width and temperature, but the contribution of the interaction between the electron and the different branches of phonons to the effective mass and the vibration frequency and the change of their variation with the well's width and temperature are greatly different. |
