We present the fabrication of GaAs/AlGaAs Multiple (from three to five) concentric nanoring structures by an innovative growth method based on droplet epitaxy and characterized by short time As supply to the Ga droplets at different substrate temperatures. The formation mechanismhas been Interpreted on the basis of a detailed ex situ and in situ characterization of nanostructure morphology and surface reconstruction, We introduce design criteria which will allow to obtain concentric quantum ring structures of the desired complexity.

Abstract

We present the fabrication of GaAs/AlGaAs Multiple (from three to five) concentric nanoring structures by an innovative growth method based on droplet epitaxy and characterized by short time As supply to the Ga droplets at different substrate temperatures. The formation mechanismhas been Interpreted on the basis of a detailed ex situ and in situ characterization of nanostructure morphology and surface reconstruction, We introduce design criteria which will allow to obtain concentric quantum ring structures of the desired complexity.
