摘要：

A terminated Magnetic Kronig-Penney model is proposed for studying electronic localized states associated with the termination (surface) of an effective potential-modulation lateral magnetic superlattice. The lateral magnetic superlattice can be created by submitting a two-dimensional electron gas to a perpendicular magnetic field periodically modulated in one direction. The existence of these localized surface states in the forbidden minigaps of the superlattice is shown explicitly and their behaviors are discussed. (C) 1997 Elsevier Science Ltd.
