Spectral signatures of high-symmetry quantum dots and effects of symmetry breaking
K. Fredrik Karlsson, Daniel Y. Oberli, Marc-André Dupertuis +6
A sequence of photoluminescence spectroscopy based methods are used to rigorously identify and study all the main spectral features (more than thirty emission lines) of site contro…
Coulomb correlations evidenced in the magneto-optical spectra of charged excitons in semiconductor quantum dots
D. Y. Oberli, M. Byszewski, B. Chalupar +3
The emission spectral pattern of a charged exciton in a semiconductor quantum dot is composed of a quadruplet of linearly polarized lines in the presence of a magnetic field orient…
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…
