摘要	We study the induced potential of an interface electron interacting with bulk longitudinal-optical (BO) phonons as well as interface optical (IO) phonons using the Green-function method. The dependence of the induced potential on the magnetic field strength and on the distance of the electron from the interface is studied. The numerical results show that in weak magnetic fields both \V(e-BO)\ and \V(e-IO)\ are rapidly increasing functions of the magnetic field, but beyond a critical magnetic field B(c), \V(e-BO)\ and \V(e-IO)\ are slowly decreasing functions of the magnetic field. The numerical results also show that the electron-IO phonon interaction is dominant for weak magnetic fields and small electron departure from the interface. In the opposite limit, the electron-BO phonon interaction is dominant.
