... Temperature-dependent CL spectra of the GaN nanorods were carried out to study the defect states of GaN nanorods. CL spectra at different positions along the length of the nanorod were also measured ... the intensity of the CL spectra at 3.4 eV became stronger. The position of the peak appearing at 3 .4 eV does not c hange with temperature, and it is ascribed to the surface st...
