| Abstract: | ome properties of a surface polaron both,strongly and weakly coupled with acoustic phonons via the deformation potential for 2D nonpolar crystals in magnetic field are studied.The ground state energy of the surface magnetopolaron is derived by the method of a linear combination operator and a Lagrange multiplier.The magnetic field dependence of vibration frequency, ground state energy and the effective mass of the surface magnetopolaron in 2D nonpolar crystals are discussed. |

| Keywords: | D nonpolar crystals deformation potential acoustic phonon surface magnetopolaron |
