Abstract
Tunneling of electrons through thin barriers in semiconductor heterostructures is usually studied via the tunnel current through multiple barrier structures.1,2 Time-resolved photoluminescence has also been used to investigate the tunneling escape rate of an electron from a quantum well (QW) bounded on each side by a thin barrier.3 We have applied the same technique to investigate the electric field dependence of this tunneling.
