Autor: Christelle Brimont, Thierry Guillet, Bernard Gil, M. Teisseire, Jean-Michel Chauveau, Luc Beaur, Dimitri Tainoff, Thierry Bretagnon

Publikováno v: physica status solidi c. 9:1320-1324

We report growth of high quality ZnO/(Zn,Mg)O quantum wells, with 20% magnesium content, on M-plane oriented ZnO substrates. The optical properties are studied by reflectance spectroscopy and continuous wave photoluminescence. The reflectance spectra

Publikováno v: Superlattices and Microstructures. 49:209-216

We present strong coupling regime between localized plasmon in lithographed nanoparticles and excitons in an organic semiconductor. The lithographed nanoparticles allow a very good control of the particle size and environment, thereby avoiding a larg

Phonon-assisted exciton formation in ZnO/(Zn, Mg)O single quantum wells grown on C-plane oriented substrates

Journal of Luminescence, Elsevier, 2013, 136, pp.355. ⟨10.1016/j.jlumin.2012.11.010⟩

We report on absorption phenomena in ZnO/(Zn, Mg)O quantum wells grown along the c-axis by molecular beam epitaxy. The optical properties of such quantum wells are affected by a huge internal electric field. For wide quantum wells the absorption is d

International audience; Photoluminescence spectra of nonpolar M-plane ZnO/Zn0.8Mg0.2O quantum wells exhibit strong excitonic peaks from low (10 K) to high (325 K) temperatures. We find that the total integrated intensity remains quasiconstant and tha
