Abstract

The spin effect of bound magnetopolaron in a triangular quantum well is investigated within Pekar variational method. The expression of the bound magnetopolaron ground-state energy is obtained through theoretical calculation. The relationship between the ground-state energy of the polaron and the wave vector, the electron areal density, the magnetic field cyclotron resonance frequency and the Coulomb bound potential is discussed, respectively. Due to the crystal structural inversion asymmetry and the time inversion asymmetry, the polaron energy experiences Rashba spin–orbit splitting and Zeeman splitting. We discussed the dominant position of Rashba effect and Zeeman effect in strong and weak magnetic fields, respectively. Due to the presence of impurities, the polaron is more stable than the bare electron state, and the energy splitting of polaron is more stable.
