Abstract

Numerous GaAs epitaxial microcrystals surrounded mainly by (111) and (110) facets having nearly equal size were grown on a sulfur(S)–terminated GaAs or GaALAs surface by sequentially supplying Ga and As molecular beams. The GaALAs layer growth over the GaAs microcrystals was performed by MEE process for burying GaAs microcrystals.
