Summary

In this chapter, nano-scale rods of titania and tungsten oxide are fabricated on metallic titanium and tungsten substrates by heat-treatment in vacuo. The surface structure and morphology are characterized by Thin-film X-ray diffraction analysis (TF-XRD) and scanning electron microscopy. The TF-XRD analysis indicated that the thermal treatment in vacuo (6.7 x10⁻² Pa) gave TiO₂ and WO₃ nano-scale rod arrays. The mechanism of the nano-scale rod array formation was explained by the structure matching due to topotaxy and the crystal growth habit.
