We theoretically investigate elastic, piezoelectric and optical properties of wurtzite GaN QDs, having hexagonal pyramid-shape which are stacked in the multilayers.  We solve the boundary-value problem using the nonlinear theory of anisotropic hyperelasticity based upon the general strain measure.  Calculated strain field is used to determine piezoelectric polarization. The spontaneous polarization is taken into acccount. The distribution of the electrostatic potential is obtained by solving the Poisson equation while the electronic states are obtained by using 8x8 kˇp hamiltonian of the wurtzite crystal.
