the temperature dependence of the properties of electron-bulk LO phonon interaction system in a quantum well within the electric-magnetic fields along the growth axis
was studied by means of variational wave-function and harmonic oscillator operator algebra method. The self energy of the system at a finite temperature was obtained. Numerical calculations for GaAs crystal show that the self-energy of the polaron in a quantum well decreases with increasing of well width and electric field and increases with increasing of temperature. The self-energy will increase with increasing of magnetic field for
