Laser field effect on binding energy and self-polarization of an impurity in a double square quantum well made of three different materials

Abstract

In this study, we investigate the variation of binding energy and self-polarization of an impurity in double square quantum wells made of three different materials, depending on the well width, laser field, and impurity position, under effective mass approximation. The subband energies are obtained by the finite difference method, and the variational method calculates the impurity energies. The binding energy and self-polarization under the effect of a laser field in a double square quantum well made of three different materials are examined in detail for the first time in this study. In double-quantum wells, it has been observed that material selection plays an important role in the calculation of binding energy and self-polarization. Studying the binding energy and self-polarization in a double square quantum well with three different materials under the effect of a laser field will enhance understanding of low-dimensional structure properties.
