Observation of the exciton Mott transition in the photoluminescence of coupled quantum wells
Gabija Kiršanskė, Petru Tighineanu, Raphaël S. Daveau +3
Indirect excitons in coupled quantum wells have long radiative lifetimes and form a cold quasi-two-dimensional population suitable for studying collective quantum effects. Here we…

Decay dynamics and exciton localization in large GaAs quantum dots grown by droplet epitaxy
Petru Tighineanu, Raphaël Daveau, Eun Hye Lee +3
We investigate the optical emission and decay dynamics of excitons confined in large strain-free GaAs quantum dots grown by droplet epitaxy. From time-resolved measurements combine…
