Abstract
Based on the compact density matrix formalism and the effective mass approximation, optical rectification of a disk-like quantum dot in the presence of impurity has been studied, in this work. The effects of applied magnetics and electric fields and its direction on the optical rectification of an elliptic anisotropic quantum dot are analyzed in details. Our results show that the optical rectification is strongly affected by the anisotropy degree and the direction of the electric field. Also, we found that the binding energies of on-center impurity can be tuned with direction of electric field and anisotropy degree.
