✦ Synopsis

With far-infrared Fourier transform spectroscopy we study the subband structure of electrons in two modulation doped GaAs/Ga,-,Al,As quantum wells which are coupled through a thin AlAs barrier grown in the center of the active GaAs layer. To facilitate the interpretation of the experimental results for this coupled double quantum well (CDQW), we also examine a barrier but otherwise identical growth single quantum well (SQW) without parameters.

Electron tunneling relaxation in double quantum wells subject to a transverse magnetic field is studied. The resonant peaks in the tunneling relaxation rate appear when the energy splitting \(\Delta\) of the tunnel-coupled pair of the left- and right- well electron states is a multiple of the cyclot
