摘要
We report on Ga nano-droplets on GaAs(100) that are not stable under arsenic flux. Spontaneous evolution in shape leads to many interesting GaAs nanostructures. GaAs nanocrystals shaped like lighted candles and square-holed round coins are observed under different growth conditions. The underlying physics of the formation of these interesting nano-structures can be understood in terms of GaAs growth under a uniform arsenic flux and a non-uniform Ga supply from the Ga nano-droplets. These novel shaped GaAs nanostructures, in an AlGaAs matrix, offer promising applications in optoelectronics. (c) 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
