The surface of an anatase titanium dioxide (TiO2) film grown on LaAlO3 was observed by noncontact atomic force microscopy (NC-AFM). After cleaning with a cycle of argon ion sputtering and annealing, (1x4) and (1x5) reconstructed terraces appeared. In addition to the terraces, the sputter-annealed surface included many agglomerations. X-ray photoelectron spectroscopy analysis showed the presence of Tin? (n=3). The low diffusivity of the Tin?(n=3) species generated by argon ion sputtering is responsible for the generation of the agglomerations.
