Abstract
The multiband effective-mass model of cylindrical self-assembled quantum dots in a magnetic field normal to the layer of the quantum dots is presented. The strain distribution is computed by the valence force field method. The strain-dependent multiband Hamiltonian is modified into an axially symmetric form, which commutes with the total angular momentum F z = fℏ, where f denotes the total magnetic quantum number. The heavy hole and the light hole parts in the mixed hole state are resolved. It is found that the heavy hole component dominates in the ground states for both f= 1 2 and f= 3 2 . The electronic structure exhibits numerous anticrossings between the hole levels. The Zeeman splitting between the +| f| and −| f| states is also computed.
