Defect free strain relaxation of microcrystals on mesoporous patterned silicon
Alexandre Heintz, Bouraoui Ilahi, Alexandre Pofelski +7
A perfectly compliant substrate would allow the monolithic integration of high-quality semiconductor materials such as Ge and III-V on Silicon (Si) substrate, enabling novel functi…
Exciton lifetime in InAs/GaAs quantum dot molecules
C. Bardot, M. Schwab, M. Bayer +3
The exciton lifetimes in arrays of InAs/GaAs vertically coupled quantum dot pairs have been measured by time-resolved photoluminescence. A considerable reduction of by…
Non-linear exciton spin-splitting in single InAs/GaAs self-assembled quantum structures in ultrahigh magnetic fields
A. Babinski, G. Ortner, S. Raymond +6
We report on the magnetic field dispersion of the exciton spin-splitting and diamagnetic shift in single InAs/GaAs quantum dots (QDs) and dot molecules (QDMs) up to = 28 T. Onl…
Correlated Photon-Pair Emission from a Charged Single Quantum Dot
S. M. Ulrich, M. Benyoucef, P. Michler +8
The optical creation and recombination of charged biexciton and trion complexes in an (In,Ga)As/GaAs quantum dot is investigated by micro-photoluminescence spectroscopy. Photon cro…
Anomalous magnetophotoluminescence as a result of level repulsion in arrays of quantum dots
E. V. Tsiper, P. D. Wang, J. L. Merz +4
Selectively excited photoluminescence (SPL) of an array of self-organized InGaAs quantum dots has been measured in a magnetic field up to 11T. Anomalous magnetic fi…
