In this article show thin films of vanadium dioxide were grown on glass and sapphire substrates by the pulsed-dc sputtering technique. To obtain the correct composition and crystal structure required the exploration of a range of conditions for deposition parameters, since there are no previous reports of VO2 growth by pulsed-dc sputtering. The crystal structure of the samples was analyzed by x-ray diffraction (XRD) and their electrical properties were characterized measuring resistance as a function of temperature. The monoclinic VO2 phase was obtained with a 90 sccm argon flux, total sputtering pressure of 6.03mTorr, oxygen partial pressure of ~ 0.33 mTorr, gun power of 300 W, 150 kHz frequency, inverse time of 2.5 µsec and substrate temperature of 550º C. Films grown on sapphire exhibited better crystal quality and their resistance change during the transition was greater than three orders of magnitude, with a narrow (3º) hysteresis curve, while those grown on glass exhibited a resistance change of over two orders of magnitude and a broad (12º) hysteresis curve.
