| Abstract(in English) | In this work, we investigated the growth conditions of n-GaN cap layer for nanowire-based laser diodes. The selective-area growth of the MQS/nanowire core-shell structures on patterned n-GaN/sapphire and GaN substrate was performed by metalorganic vapour phase epitaxy. Further, the core-shell structures were covered with the tunnel junction and the n-GaN cap layer. A two-step growth of n-GaN cap layer was carried out under various growth conditions. The improvement in surface flatness and void reduction in between the nanowires was confirmed by scanning electron microscope observation. In addition, reasonably low operating voltage and distinct light emission were observed in the electroluminescence measurements. |
