Abstract
Tunneling in asymmetric double quantum wells is studied using time-res olved photoluminescence. The photoluminescence lineshape and peak posi tion of the narrow quantum well are strongly influenced by band-gap re normalization caused by the tunneling carriers. Tunneling is quenched in a field regime of +/- 10 kV/cm around the ground state resonance du e to excitonic effects.
