摘要：

Time dependent resonant tunneling of electron wave packets scattered through symmetric and asymmetric double barrier heterostructures under an external electric field is studied by systematically varying the barrier lengths. The different times involved. the charging time, the dwell time, the life time and passage time by transmission, are examined and grouped according to their qualitative behaviour against the barrier widths. It is found that the life time and dwell time are not always proportional.
