โœฆ Synopsis


Tunneling absorption is calculated in weakly-coupled n-type asymmetric double quantum wells in an in-plane magnetic field using a linear response theory. Tunneling absorption of photons occurs between the ground sublevels of the quantum wells. We show that the absorption threshold, the resonance energy of absorption, and the linewidth depend sensitively on the magnetic field and the temperature.

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

We present essentially exact calculations of excitonic absorption spectra in quantum wells including the effects of Coulomb mixing between sub-bands. Spectra are calculated for a range of well widths, covering the transition from two to quasi-three dimensional behaviour. The high resolution spectra
