Transformation of concentric quantum double rings to single quantum rings with squarelike nanoholes on GaAs(001) by droplet epitaxy

The fabrication of self-assembled InxGa1−xAs nanostructures on GaAs(001) substrates grown by droplet epitaxy using molecular beam epitaxy is reported. The effect of In contents (0≤x≤0.2) for InxGa1−x droplets on their shape, dimension, density, and depth profile was investigated. The concentric quan...
