The effect of strain and magnetic field on the interband nonlinear refractive index in an anisotropic disc shaped quantum dot in the presence of a Gaussian impurity

in this paper, the interband nonlinear refractive index of a disc shaped anisotropic quantum dot has been theoretically studied. Using the perturbation method, the effects of the strain, magnetic field and anisotropy degree in the presence Gaussian impurity has been investigated. It has been shown that the interband nonlinear refractive index in the presence Gaussian impurity with increasing magnetic field shift to higher energies and with the increasing anisotropy shift to lower energies
