Experimental demonstration of a Two-Dimensional Hole Gas (2DHG) in a GaN/AlGaN/GaN based heterostructure by optical spectroscopy
Loïc Méchin, François Médard, Joël Leymarie +5
The polarization discontinuity across interfaces in polar nitride-based heterostructures can lead to the formation of two-dimensional electron and hole gases. In the past, the obse…
Lasing in a ZnO waveguide: clear evidence of polaritonic gain obtained by monitoring the continuous exciton screening
Geoffrey Kreyder, Léa Hermet, Pierre Disseix +7
The stimulated emission of exciton-polaritons was proposed as a means of lowering the lasing threshold because it does not require the dissociation of excitons to obtain an electro…
LO-phonon assisted polariton lasing in a ZnO based microcavity
L. Orosz, F. Réveret, F. Médard +13
Polariton relaxation mechanisms are analysed experimentally and theoretically in a ZnO-based polariton laser. A minimum lasing threshold is obtained when the energy difference betw…
Fabrication and Optical Properties of a Fully Hybrid Epitaxial ZnO-Based Microcavity in the Strong Coupling Regime
L. Orosz, F. Réveret, S. Bouchoule +11
In order to achieve polariton lasing at room temperature, a new fabrication methodology for planar microcavities is proposed: a ZnO-based microcavity in which the active region is…
From Strong to Weak Coupling Regime in a Single GaN Microwire up to Room Temperature
A. Trichet, F. Médard, J. Zuniga-Perez +2
Large bandgap semiconductor microwires constitute a very advantageous alternative to planar microcavities in the context of room temperature strong coupling regime between exciton…
