Abstract

Anomalous X-ray scattering from self-assembled PbSe quantum dots embedded in Pb 1− x Eu x Te was used for the study of their structure. The measured reciprocal-space distributions of diffracted intensity were compared with simulations based on kinematical scattering theory and continuum elasticity. From the comparison, the mean chemical composition of the dots and their aspect ratio (height/width) were estimated.
