Abstract Thin films of MoS2 and Ti-MoS2 were deposited on Si substrate by using magnetron sputtering respectively, and then oxidized in atmosphere with 70%RH at 28℃ for 360 h via a temperature and humidity chamber. Thereafter, the oxidation performance and electrical properties of the above two MoS2 films were characterized by XRD, XPS, UV-Vis spectrophotometer and four-point probe method. The results show that the Ti doping can affect the crystal orientation of MoS2 film, and the X-ray diffraction peaks of (110) and (100) of MoS2 disappear after Ti doping. The films prepared with applied current of 0.6 A for Ti-target are amorphous. Whilst, the band gap of Ti-MoS2 decrease and the conductivity increase for films, with the increasing applied current for the Ti target. The films are partially oxidized and present the composite state of MoS2 and MoO3 after oxidation in the atmosphere with 70%RH at 28℃ for 360 h, and the IMo-O/IMo-S ratio and band gap increase with the increasing applied current for the Ti target. Especially, the Ti-MoS2 film, prepared with applied current of 0.4 A for the Ti target, exhibits the better chemical stability.
