Temperature Dependent Exciton Funnel Dynamics in Uniform Strain Gradient Field Observed by Time-Resolved Photoluminescence

Benoît Marie Joseph Deveaud, Jean-Daniel Ganière, Mehran Shahmohammadi, Gwénolé Jean Jacopin

Elastic strain engineering is an important way to reversibly tune the properties of micro/nanoscale semiconductors for promising applications in the emerging advanced nanotechnologies, such as the strain enhanced high-mobility transistors, nanogenerators, ...

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

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

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 ...

Excitonic Diffusion in InGaN/GaN Core–Shell Nanowires

Jean-Daniel Ganière, Hua Zhang, Mehran Shahmohammadi, Gwénolé Jean Jacopin

We report on the direct observation of the diffusion of carriers in graded InGaN/GaN quantum wells in a nanowire. By probing the local dynamics at the nanoscale, along the wire for different temperatures between 4 and 250 K, we conclude that this diffusion ...
