On the condition of electron-LO-phonon strong coupling in a parabolic quantum dot
we obtained the ground-state energy of polaron by using Pekar type variation method.The relations between the ground energy and the electron-LO-phonon coupling strength
the confinement length
the temperature were discussed.The results indicate that the ground energy of polaren in a parabolic quantum dot will decrease with increasing the electron-LO-phonon coupling strength and the confinement length and increase with increasing the temperature.
