Abstract
A self-consistent calculation of the traversal time in a resonant tunneling device has been presented. The model is then used to study the effect of a transverse magnetic field on the traversal time. The calculation shows the presence of bistability in the traversal time. It is also observed that the traversal time becomes progressively longer in the presence of increasing magnetic field. A quantity called the effective traversal time has been defined which can be compared to an important time scale, namely, the carrier thermalization time, and may be experimentally measurable.
