| 英文摘要 | we investigate the controllable negative and positive group delay in transmission through a single quantum well at the finite longitudinal magnetic fields. it is shown that the magneto-coupling effect between the longitudinal motion component and the transverse landau orbits plays an important role in the group delay. the group delay depends not only on the width of potential well and the incident energy, but also on the magnetic-field strengthen and the landau quantum number. the results show that the group delay can be changed from positive to negative by the modulation of the magnetic field. these interesting phenomena may lead to the tunable quantum mechanical delay line.
