Abstract

The strain field in semiconductor core multi-shell quantum dots is obtained within linear continuum elasticity approach. Concrete expressions are provided for one and two shells in spherical and cylindrical symmetry. The model is applied to several typical heterostructures. The hydrostatic strain of the core is found to be strongly dependent on the thickness and elastic parameters of the shells..
