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…
Influence of magnetic quantum confined Stark effect on the spin lifetime of indirect excitons
P. Andreakou, A. V. Mikhailov, S. Cronenberger +7
We report on the unusual and counter-intuitive behaviour of spin lifetime of excitons in coupled semiconductor quantum wells (CQWs) in the presence of in-plane magnetic field. Inst…
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…
