The evolution
of self-assembled Au droplets depending on the surface index showed quite similar behavior in terms of the size and density evolution. This can be due to the minor index effect when the diffusion length is fixed by the fixed annealing temperature; it could also be due to the excessive degree of change in the size and density of Au droplets. This result can be promising in various related nanostructure fabrications: quantum size effect, nanowires, biosensing, catalysis, study on the improvement of the localized surface plasmonic resonance, etc. on GaAs (111)A and (100) surfaces.
