中文摘要	The self-energy of an interface electron interacting with bulk longitudinal-optical phonons as well as interface optical (IO) phonons in a magnetic field of arbitrary strength is studied using the Green function method. Our results show that the absolute value \E(e-ph)((0))\ of the ground-state self-energy of the electron is a rapidly increasing function of the magnetic field in the weak-magnetic-field region, but \E(e-ph)((0))\ is a slowly decreasing function of the magnetic field beyond a critical magnetic field B-c. For the excited states, \E(e-ph)((n))\(n greater than or equal to 1) is an increasing function of the magnetic field in the pre-resonant region, while E(e-ph)((n)) is a positive and decreasing function of the magnetic field beyond the resonant region. Numerical results show that the electron-IO phonon interaction contributes only when the mean distance of the polaron from the interface is small and in the extremely-weak-magnetic-field region.
