The effects of the magnetic and non-resonant intense laser fields on the electronic and optical properties of the shifted Deng–Fan type quantum well

Abstract

The aim of this study is to examine how the magnetic field, the non-resonant intense laser field, and the well sizes affect the energy spectrum and intraband transitions of electrons confined within a quantum well modeled with a shifted Deng–Fan molecular potential. The calculations were performed within the effective mass and parabolic band approximation frameworks. These investigations have involved analyzing the energy spectrum and determining both the linear and third-order nonlinear absorption coefficients. To obtain the solution of the Schrödinger equation for the system, the diagonalization technique was applied using a set of orthonormal basis functions. The calculation of the absorption coefficients both linear and third-order nonlinear components were carried out using the conventional density matrix approach in conjunction with the perturbative expansion method. Our results reveal critical tunability of the optical absorption characteristics through well size, magnetic field strength, and intense laser field parameters.
