In this study, vanadium dioxide (VO(subscript 2)) nanowires were synthesized using chemical vapor deposition on Si substrate by pure vanadium. Field emission scanning electron microscope (FESEM) image showed vanadium dioxide nanowires were about 50~100nm, the length achieve several micrometers. High resolution transmission electron microscopy (HRTEM) indicated that VO(subscript 2) nanowires all were single-crystalline structure. X-ray diffraction (XRD) indicated that the structures of VO(subscript 2) nanowires were monoclinic. In addition, the components were analysis by energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). Finally, we used a simple way to test voltage-current and found out electrical properties.
