Abstract
We have fabricated highly packed and ordered In0.4Ga0.6As quantum dots (QDs ) array on GaAs(311)B substrate without coalescence of QDs. Reflection high -energy electron diffraction and Auger spectra suggest the inhomogeneous di stribution of In and Ga in QD. In concentration near the surface of QD is l arger than that of the inside, and the inhomogeneous distribution of In and Ga in QDs prevents QDs from merging. (C) 1998 American Institute of Physic s.
