Abstract
In this review, we have investigated theoretically the third-order nonlinear optical susceptibility in Ge/Si0.15Ge0.85 spherical core/shell quantum dots under electric field (EF) for both cases with and without on-center impurity within the framework of the compact-density-matrix (C.D.M). The eigenenergies and their corresponding wave functions of the system are computed by solving the three-dimensional Schrödinger equation using the effective mass approximation (E.M.A) using the variational method (VM). Our computational results show that both the energy levels and the third-order nonlinear optical susceptibility are strongly affected by the quantum dot size, the effects of the hydrogenic impurity, and the electric field intensity.
