非对称抛物限制势量子点中强耦合束缚磁极化子的性质

The properties of a bound magnetopolaron with electron-LO-phonon strong-coupling in quantum dots with an unsymmetrical parabolic confinement potential are investigated using the Pekar type variational method.The ground state binding energy and the average number of virtual phonons around the electron of the bound magnetopolaron are derived.Numerical calculations indicate that both the ground state binding energy and the average number of virtual phonons around the electron increase with increasing lateral confinement strength,longitudinal confinement strength, and cyclotron frequency.Numerical calculations also indicate that the ground state binding energy increases with increasing coulomb potential.
