Enhancement of the Binding Energy of Charged Excitons in Disordered Quantum Wires
T. Otterburg, D. Y. Oberli, M. -A. Dupertuis +5
Negatively and positively charged excitons are identified in the spatially-resolved photoluminescence spectra of quantum wires. We demonstrate that charged excitons are weakly loca…

Excitonic lasing in semiconductor quantum wires
L. Sirigu, D. Y. Oberli, L. Degiorgi +2
Direct experimental evidences for excitonic lasing is obtained in optically pumped V-groove quantum wire structures. We demonstrate that laser emission at a temperature of 10 K ari…
