Simulation with interacting-potentials has been performed to investigate hole distribution in La2−xSrxCu1−yZn(Ni)yO4(y=1/32 and x⩽1/8). It is found that the orderly distributed hole configurations are more energetically favorable than the randomly distributed hole configurations. Moreover, the doped Zn2+and Ni2+ions can both act as stabilizing centers to localize the holes in their vicinity leading to an atomic-scale inhomogeneous distribution of holes. This atomic-scale inhomogeneities of holes obtained from our simulation is similar to that predicted by the “Swiss Cheese” model.
