Renormierung der Bandlücke und exzitonische Effekte bein Tunneln in asymmeterischen Doppel Quantum Wells
Abstract
Tunneling in asymmetric double quantum wells is studied using time-resolved hotoluminescence. The photoluminescence lineshape and peak position of the narrow quantum well are strongly influenced by band-gap renormalization caused by the tunneling carriers. Tunneling is quenched in a field regime of Ï 10 kV/cm around the groundstate resonance due to excitonic effects.
