    • We examined the dipole moment perpendicular to the surfaces of perfect LaMnO3, defective LaMnO3 with one oxygen vacancy, and La0.5Sr0.5MnO3 with one oxygen vacancy (2.89, 2.55, and 2.53 D, respectively, the results suggest that the dipole moment of the asymmetric surface models with eight atomic layers was slightly reduced by the presence of oxygen vacancies. When seven-atomic-layer symmetric surface models terminated with O or LaMn were used, their dipole moments cancelled out see ref, 8
