Abstract

The self-assembled pure isotope Ge/Si(100) quantum dots (QD) were studied using Raman scattering. It was shown that the intermixing in the QDs depends on the dot size, is stronger in smaller dots and the germanium rich area exists as a core of the dots. It was also shown that the amplitude of the Raman peak is not directly proportional to the number of the corresponding bonds in the sample.
