Polyerystalline TiO2 surface reconstruction in oxygen atmosphere has been investigated by atomic force microscopy (AFM) and cathodoluminescence in the scanning electron microscopy (SEM-CL). The reactivity to oxygen is related to the presence of defects as interstitial Ti ions, that induce growth of protrusions, large terraces and polygonal shaped structures.
