| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 92 === SnO2 nanowires were synthesized using a direct gas reaction route and 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 SnO2 nanowires with lattice parameters of a = 4.73 Å、 c = 3.17 Å. Three vibrational modes were observed in the Raman spectra of the samples.
According to the current-voltage (I-V) measurements, we know that the sensitivity of SnO2 nanowires is much higher than SnO2 thin film because of the high surface-to-volume ratio of nanowires.
