Exciton-phonon interaction in the strong coupling regime in hexagonal boron nitride
T. Q. P. Vuong, G. Cassabois, P. Valvin +3
The temperature-dependent optical response of excitons in semiconductors is controlled by the exciton-phonon interaction. When the exciton-lattice coupling is weak, the excitonic l…
Transport of dipolar excitons in (Al,Ga)N/GaN quantum wells
F. Fedichkin, P. Andreakou, B. Jouault +8
We investigate the transport of dipolar indirect excitons along the growth plane of polar (Al,Ga)N/GaN quantum well structures by means of spatially- and time-resolved photolumines…
Laser emission with excitonic gain in a ZnO planar microcavity
Thierry Guillet, Christelle Brimont, Pierre Valvin +8
The lasing operation of a ZnO planar microcavity under optical pumping is demonstrated from T=80 K to 300 K. At the laser threshold, the cavity switches from the strong coupling to…
Preliminary results on the Extinction and Night Sky Background in UBV on La Silla and ALMA site
E. Giraud, G. Vasileiadis, P. Valvin +1
We report on measurements of the extinction in the U, B & V bands and of the NSB (Night Sky Background) during 2 dark periods on La Silla Observatory and at 4000-5000m on the ALMA…
