Magnetopolaron Energy Level in Parabolic Semi-exponential RbCl Quantum Wells in Magnetic Impurity Field

The polaron, a quasiparticle system formed by the interaction of electrons and phonons in quantum well (QW) materials, is very important for the photoelectric properties of low-dimensional materials. Therefore, the ground state binding energy (GSBE) and vibration frequency (VF) of magnetic-impurity polaron in a QW system subjected to parabolic potential in x and y directions and semi-exponential potential in z direction are studied by unitary transformation and variational method. We found that the VF and GSBE with magnetic field cyclotron frequency (MFCF), the parameter of the asymmetrical semi-exponential confinement potential (ASECP), effective confinement lengths (ECL) of the Coulombic impurity potential (CIP). The above results not only show the quantum size effect of materials but also provide a theoretical idea for regulating the polaron effect.
