Abstract: Abstract This theoretical study investigates the weak, intermediate, and strong coupling strength dependence of piezoelectric polaron properties of asymmetric Gaussian GaAs, CuCl, and RbCl quantum wells. We employed the modified Lee–Low–Pines (LLP) transformation and the linear combination operation method to compute the ground state energy, binding energy, magnetic moment, and magnetic susceptibility. It is shown that the magnetic field, electric field, quantum well range, well depth, the Debye cutoff wavenumber (DCOW), and electron–phonon coupling strengths are important factors that have a significant influence on the piezoelectric polaron properties of an asymmetric Gaussian quantum wells. The significant contribution of this study to the field underscores its value and importance to the academic community in this field. Graphical abstract
