The classical problem of a time-modulated barrier, inspired by the Buttiker and Landauer model to study the tunneling αΊ—imes, is analyzed. We show that the traversal-time distribution of an ensemble of non-interacting particles that arrives at the oscillating barrier, obeys a distribution with a powe

The phase time of an electron tunneling through a heterostructure potential barrier is derived, including the position-dependent effective-mass effect. The usual phase time of the tunneling derived assuming a homogeneous effective mass deviates from this result by \(-15 \% \sim-28 \%\).
