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…
Electrical control of excitons in GaN/(Al,Ga)N quantum wells
R. Aristegui, F. Chiaruttini, B. Jouault +7
A giant built-in electric field in the growth direction makes excitons in wide GaN/(Al, Ga)N quantum wells spatially indirect even in the absence of any external bias. Significant…
Complexity of dipolar exciton Mott transition in GaN/(AlGa)N nanostructures
F. Chiaruttini, T. Guillet, C. Brimont +6
The Mott transition from a dipolar excitonic liquid to an electron-hole plasma is demonstrated in a wide GaN/(Al,Ga)N quantum well at K by means of spatially-resolved magneto-…
Dipolar excitons offer a rich playground for both design of novel optoelectronic devices and fundamental many-body physics
F. Chiaruttini, T. Guillet, C. Brimont +6
Dipolar excitons offer a rich playground for both design of novel optoelectronic devices and fundamental many-body physics. Wide GaN/(AlGa)N quantum wells host a new and promising…
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…
Transport of indirect excitons in ZnO quantum wells
Yuliya Kuznetsova, Fedor Fedichkin, Peristera Andreakou +8
We report on spatially- and time-resolved emission measurements and observation of transport of indirect excitons in ZnO/MgZnO wide single quantum wells.
