Large size self-assembled quantum rings: quantum size effect and modulation on the surface diffusion

We demonstrate experimentally the submicron size self-assembled (SA) GaAs quantum rings (QRs) by quantum size effect (QSE). An ultrathin In(0.1) Ga(0.9)As layer with different thickness is deposited on the GaAs to modulate the surface nucleus diffusion barrier, and then the SA QRs are grown. It is f...
