dc.description.abstractThe present study examines the electronic and optical properties of Rosen-Morse quantum wells, which exhibit hyperbolic and exponential potential profiles, subjected to intense laser fields and electric fields. Calculations are performed within the framework of the effective mass and parabolic band approximations. To determine the eigenvalues of electrons confined in these potentials, the diagonalization method was employed, utilizing orthonormal base functions that are solutions of an infinite square quantum well. To calculate the total absorption coefficient, including linear and nonlinear terms for transitions between the lowest two energy levels, a combination of the standard density matrix formalism and the perturbation expansion method was employed. Our results indicate that intense laser field is a valuable tool for controlling the confinement potential of low-dimensional systems, enabling the appropriate tuning of these systems. While the electric field applied only to symmetrical structures breaks the symmetry and causes the peaks in the absorption spectrum to shift to red, a blue shift of the absorption peaks was achieved with the combined effect of the selected geometric shapes of the quantum wells and the electric field. Therefore, it is hoped that the obtained results will provide important improvements in device applications with a suitable choice of both fields and structure parameters.
