Physical properties of hydrothermal growth nanostructure metal titanium dioxide

Growth of titanium dioxide (TiO₂) nanowires was studied on the seed layer of TiO₂ through hydrothermal growth method. Here, the growth of nanowires TiO₂ on Si (100) substrates by using the two steps method. Different seed layers of TiO₂ were prepared by using sol-gel method, deposited by spin coating and annealing, followed by the growth of TiO₂ nanowires by using the hydrothermal method. Acetic acid was used as a stabilizer to synthesize a TiO₂ seed layer. The aim of this study was to understand the role of polycrystalline size on thin film towards the diameter of nanowires grown as a sensing area in Surface Acoustic Wave (SAW) Biosensor. The morphology and microstructure of the thin film seed layer and TiO₂ nanowires were characterized using X-Ray diffraction (XRD), scanning electron microscope (SEM), field emission scanning electron microscope (FESEM) and atomic force microscopy (AFM).
