主　　题：Droplet epitaxy aluminum droplets MBE GaAs holed nanostructures 

摘      要：We have studied the morphology evolution of holed nanostructures formed by aluminum droplet epitaxy on a GaAs *** outer rings with concentric inner holed rings were ***,an empirical equation to describe the size distribution of the outer rings in the holed nanostructures has been *** contour line generated by the equation provides physical insights into quantum ring formation by droplets of groupⅢmaterials onⅢ-Ⅴsubstrates.
