Room-temperature transport of indirect excitons in (Al,Ga)N/GaN quantum wells
F. Fedichkin, T. Guillet, P. Valvin +7
We report on the exciton propagation in polar (Al,Ga)N/GaN quantum wells over several micrometers and up to room temperature. The key ingredient to achieve this result is the cryst…

Large K-exciton dynamics in GaN epilayers: the non-thermal and thermal regime
A. Vinattieri, F. Bogani, L. Cavigli +7
We present a detailed investigation concerning the exciton dynamics in GaN epilayers grown on c-plane sapphire substrates, focussing on the exciton formation and the transition fro…

Magneto-photoluminescence of GaN/AlGaN quantum wells: valence band reordering and excitonic binding energies
P. A. Shields, R. J. Nicholas, N. Grandjean +1
A re-ordered valence band in GaN/AlGaN quantum wells with respect to GaN epilayers has been found as a result of the observation of an enhanced g-factor in magneto-luminescence spe…
