Analysis of the 3D distribution of self-assembled stacked quantum dots by electron tomography

Materials Science 2012-10-25 v4

Abstract

This paper has been withdrawn by the authors. The 3D distribution of self-assembled stacked quantum dots (QDs) is a key parameter to obtain the highest performance in a variety of optoelectronic devices. In this work, we have measured this distribution in 3D using a combined procedure of needle-shape specimen preparation and electron tomography. We show that conventional 2D measurements of the distribution of QDs are not reliable, and only a 3D analysis allows an accurate correlation between the growth design and the structural characteristics.
