Abstract
In situ Ga-catalyzed AlGaAs nanostructures have been grown by MOVPE. The effect of growth temperature on the shape, size, tapering, and spatial distribution of nanostructures has been investigated using the FESEM technique. Micro-PL measurements have been conducted to analyze the optical quality of the nanostructures. Aluminum composition of around 13% has been estimated by multiple peak-fitting of the PL spectrum.
