Strain field calculations of quantum dots - A comparison study of two methods
The elastic strain field plays a crucial role during the self-organized growth of semiconductor quantum dot structures in the Stranski-Krastanov growth mode. Several theoretical methods have been developed for calculating the strain field of these lattice-mismatched systems. In this report we present a study exemplarily comparing an atomistic approach and calculations using elasticity theory. Features, limitations and selected possible applications of both approaches are discussed.
