dc.description.abstractThis work has explored the behavior of an electron traversing a two-dimensional InAs quantum ring, affected by an off-center impurity and exposed to a magnetic field. These investigations have involved analyzing the energy spectrum and determining both linear and non-linear absorption coefficients. To solve the Schrodinger equation of the system, the numerical diagonalization method was utilized by using by choosing orthonormal base functions that are solutions of two-dimensional isotropic harmonic oscillator. For the absorption coefficients including the linear and third-order nonlinear terms the standard density matrix formalism combined with the perturbation expansion method is used.
