MOVPE grown self-assembled Sb-based quantum dots assessed by means of AFM and TEM

Abstract:

Self-assembled Sb-based quantum dots (QDs) were grown by metal-organic vapour phase epitaxy and assessed by means of atomic force microscopy, transmission electron microscopy and photoluminescence. Two series of InSb QDs in a GaSb matrix were grown at 490 +/- 10 degrees C and luminesced in the mid-infrared at about 1.7 mu m. Reductions in the III/V ratio and growth rate as used for the second series resulted in a change of the morphology of the InSb islands from hillocks without facets and a ...
