| Abstract(in English) | Spatial and time-resolved spectroscopy system having laser pulse-width of 266nm, spatial resolution of a few microns and time resolution of 2ps has constructed. By means of this measurement system, recombination of carriers in GaN-based layers having different dislocation density has assessed. It was found that photoluminescence (PL) was dominated by A-free exciton and nonradiative recombination channel in each sample at room temperature. Moreover, it was found that threading dislocations do hardly affect nonradiative recombination lifetime (τ_ |
