摘要：

Magnetoquantum oscillations in the tunnel current of wide In0.53Ga0.47As/In0.52Al0.48As double quantum wells have been exploited to trace the energy levels in the adjacent wells as a function of the applied voltage. The dominant inelastic scattering mechanism was identified as GaAs-like longitudinal-optical-phonon emission. This powerful spectroscopy probe allows an unambiguous identification of the transmission channels responsible for the peaks observed in the current-voltage characteristics and provides a large number of consistency checks. The obtained experimental results can be used to verify the accuracy of self-consistent simulation programs.
