Abstract: An analytical method based on Green's function for calculating strain filed in quantum dot structures of arbitrary shape was presented. The method involves the evaluation of a surface integral over the boundary of the quantum dot. The strain distributions for some shapes as pyramid and cone were discussed. Compare to the element method, our method is more straightforward and faster to implement, and it is also particularly well suited as an input step in calculation of the electronic properties of quantum dots.

Key words: quantum dots, stress and strain distribution, Green method
