In this paper, tin dioxide (SnO 2 ) nanowires were synthesized on silicon substrate (111) using a direct gas reaction route on a large scale at 700°C 1000°C. These SnO 2 nanowires were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman-scattering spectroscopy. XRD, SEM and TEM indicated that the products were tetragonal SnO 2 nanowires with lattice parameters of a = 4.73 , c = 3.17 . Three vibrational modes were observed in Raman spectra of the samples. According to the current-voltage (I-V) measurements, Tin dioxide nanowires can be used as a sensor.
