Influence of surface structure on the phonon-assisted emission process in the ZnO nanowires grown on homoepitaxial films
We carried out temperature-dependent photoluminescence measurements to investigate the influence of surface roughness on the phonon-assisted emission of the surface-tailored ZnO nanowires (NWs). For the rough ZnO NWs, the observation of strong defect emission with vibration peaks by the exciton-phon...
