Group-III nitride nanowire (NW) ensembles have been employed for a wide range of applications, especially optoelectronic devices [1
where only one major, slightly asymmetric emission band was visible. A similar band profile of the EL spectra of single NWs has already been reported in the literature [4][7]. Hence, we assume that spectrum C shows the luminescence of a single nanowireLED.
In order to better understand the emission
