Abstract :
In this study, GaN nanocolumns was fabricated through RF-plasma assisted molecular beam epitaxy on sapphire substrate. SEM was used for nanocolumn structure analysis. Photoluminescence image of InGaN-single quantum well at the top of each nanocolumn was detected at each near-field scanning optical microscopy (NSOM)scanning point. The intensity was observed to decrease exponentially which was attributed to Anderson localization.
