Abstract

We apply time-resolved four-wave mixing as a novel tool to study resonant tunneling of carriers in semiconductor heterostructures. The polarization decay of excitons in a quantum well is much faster when the alignment of the electron levels in adjacent wells leads to resonant tunneling and subsequent scattering of the carriers.
