InAs Nanoscale Islands on Si Surface: A New Type of Quantum Dots
Abstract
We study epitaxial growth of InAs on Si(100) surface using molecular beam epitaxy. We found that at moderate arsenic fluxes and substate tempeartures (470 C) the growth proceeds in Stranski-Krastanow growth mode with formation of mesoscopic dislocated clusters on top of the two-dimensional periodically-corrugated InAs wetting layer. At lower temperatures (250 C) a dense array of selof-orgarnized nanoscale InAs quantum dots with good size and shape uniformity is formed.
