Abstract

In this paper, we investigate the cumulative effects of magnetic field and spin–orbit interaction (SOI) on the magnetopolaron-excited binding energy in RbCl semi-exponential quantum well material using Lee Low Pines Unitary Transformation and Linear Combination operator method. It’s shown that, the excited binding energy is strongly modified under the superposition of SOI and magnetic field. The predominant contribution is coming from the magnetic field strength compared to SOI constant \(\alpha_{r}\). Although neither the magnetic field nor the SOI can be neglected during the investigation of the properties of magnetopolaron, the barrier height of semi-exponential quantum well \(U_{0}\), the number of phonon \(N\) and the spin–orbit interaction affect considerably the excited state binding energy. This analysis reveals the importance in nanotechnology of RbCl material due to the variability of their property.
