Magneto-optical analysis of anisotropic CdZnSe quantum dots

The effect of magnetic field and geometrical anisotropy on electronic and optical properties of self-assembled CdZnSe quantum dots is theoretically investigated. The Luttinger Hamiltonian formulation has been used in a transformed coordinate system for obtaining the energy eigenvalues and wavefunctions for the holes. The variation of energy eigenvalues with the magnetic field has been studied for anisotropic quantum dots. The degree of linear polarization is also calculated and is found to increase with magnetic field which is explained in terms of anisotropy induced valence subband mixing.
