Nuclear spin relaxation mediated by donor-bound and free electrons in wide CdTe quantum wells
Boris F. Gribakin, Valentina M. Litvyak, Mladen Kotur +4
The nuclear spin systems in CdTe/(Cd,Zn)Te and CdTe/(Cd,Mg)Te quantum wells (QW) are studied using a multistage technique combining optical pumping and Hanle effect-based detection…
Molecular beam epitaxy of GaN/AlGaN quantum wells on bulk GaN substrate in the step-flow or step meandering regime: influence on indirect exciton diffusion
Benjamin Damilano, Rémi Aristégui, Henryk Teisseyre +8
GaN/AlxGa1-xN quantum wells were grown by molecular beam epitaxy on high quality bulk (0001) GaN substrates. The quantum well thickness was set in the 6-8 nm range to favor the pho…
Electrostatic modulation of excitonic fluid in GaN/AlGaN quantum wells by deposition of few-layered graphene and nickel/gold films
R. Aristegui, P. Lefebvre, C. Brimont +9
Excitons hosted by GaN/(Al,Ga)N quantum wells (QWs) are spatially indirect due to the giant built-in electric field that separates electrons and holes along the growth direction. T…
Exciton dynamics in CdTe/CdZnTe quantum well
A. V. Mikhailov, A. S. Kurdyubov, E. S. Khramtsov +6
Exciton energy structure and population dynamics in a wide CdTe/CdZnTe quantum well are studied by spectrally-resolved pump-probe spectroscopy. Multiple excitonic resonances in ref…
Nuclear spin relaxation in n-GaAs: from insulating to metallic regime
M. Vladimirova, S. Cronenberger, D. Scalbert +7
Nuclear spin relaxation is studied in n-GaAs thick layers and microcavity samples with different electron densities. We reveal that both in metallic samples where electrons are fre…
Nonlinear optical spectroscopy of indirect excitons in biased coupled quantum wells
P. Andreakou, S. Cronenberger, D. Scalbert +9
Indirect excitons in coupled quantum wells are long-living quasi-particles, explored in the studies of collective quantum states. We demonstrate, that despite the extremely low osc…
