| Abstract: | The properties of magnetopolaron in purely 2D polar crystals,coupling with optical phonon,was studied.The mean number of optical phonons in the cloud around the strong and weak-coupling electron in purely 2D polar crystals is derived by using unitary transformation and linear combination operator method for a magnetic field.Numerical calculations,for the AgCl crystal,as an example,are performed and some properties of the vibration frequency,the mean number of optical phonon of magnetopolaron in purely 2D polar crystals are discussed. |
