【Abstract】 Taking into account the interaction of an electron with both Lo and So phonorts as well as the image potential at finite temperature, we study the’ effective Hamiltonian of a polaron in a semi-infinite polar crystal. The temperature dependence on the self-induced polaron potential, the effective maas and the depth of the dead layer is given.更多还原
