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 ...
