摘要：

We have studied the dynamics of electrons in a Ga1-xAlxAs-GaAs asymmetric double quantum well heterostructure under an external applied electric field. In this coupled quantum well system, we show that direct observation is possible of an oscillating luminescence signal with a quantum tunnelling period modulated by means of an applied longitudinal magnetic field.
