Enhancement of Auger recombination induced by carrier localization in InGaN/GaN quantum wells

Nicolas Grandjean, Benoît Marie Joseph Deveaud, Raphaël Butté, Gwénolé Jean Jacopin, Wei Liu, Georg Rossbach, Lise Lahourcade, Mehran Shahmohammadi

The origin of efficiency droop in state-of-the-art quality In GaN/GaN and GaN/AlGaN quantum wells (QWs) grown on various crystal planes is studied by means of time-resolved photoluminescence spectroscopy associated with a precise determination of the QW ca ...

Critical impact of Ehrlich-Schwobel barrier on GaN surface morphology during homoepitaxial growth

Nicolas Grandjean, Denis Martin, Lise Lahourcade, Nils Asmus Kristian Kaufmann

We discuss the impact of kinetics, and in particular the effect of the Ehrlich-Schwobel barrier (ESB), on the growth and surface morphology of homoepitaxial GaN layers. The presence of an ESB can lead to various self-assembled surface features, which stron ...

InGaN laser diodes emitting at 500 nm with p-layers grown by molecular beam epitaxy

Nicolas Grandjean, Julien Dorsaz, Eric Feltin, Antonino Francesco Castiglia, Marco Malinverni, Jean-Michel Jacques Lamy, Marco Rossetti, Lise Lahourcade, Denis Martin

We demonstrate hybrid laser diodes by combining n-type layers and an active region grown by metal organic vapor phase epitaxy with p-type layers grown by molecular beam epitaxy. These p-doped layers, grown at 740 degrees C, exhibit state-of-the-art electri ...
