“…At room temperature, the specific conductance was found to be in the order of 10 -3 to 10 -2 (X cm) -1 , which agrees well with the earlier reported value (Hankare et al 2009a;Sathe et al 2010). It is observed that the conductivity of the film increases with increase in temperature.…”

Nanocrystalline tungsten diselenide thin films have been deposited on non-conducting glass and stainless steel substrates by chemical methods. Various preparative conditions were optimized for the formation of thin films. The X-ray diffraction analysis shows that the film samples are in layer-hexagonal crystal structure. EDAX analysis shows that the films are nearly stoichiometries of W:Se. Optical properties show a direct band gap nature with band gap energy 1.5 eV. Specific electrical conductivity was found to be in the order of 10 -3 to 10 -2 (X cm) -1 . The photoelectrochemical characterization of the films was carried out by studying current-voltage characteristics, capacitance-voltage and power output characteristics. The efficiency of photoelectrode was found to be 1.31 % using iodine-poly iodide electrolyte.

“…At room temperature the specific conductance was found to be in the order of 10 À5 (U cm) À1 , which agrees well with the earlier reported value [22,23]. The low value of conductivity may be attributed to the nanocrystalline nature of thin film, crystallite boundary discontinuities, presence of surface states and small thickness of the film.…”

Preparation of layered type semiconductor Mo 0.5 W 0.5 S 2 -thin films has been successfully done by using chemical bath deposition method. Objective of the studies are related to structural, optical, morphological and electrical properties of the thin films. The preparation method is based on the reaction between tartarate complex of Mo and W with thiourea in an aqueous alkaline medium at 363 K. X-Ray diffraction reveals a polycrystalline film composed of both MoS 2 and WS 2 phases. The optical study shows that the band gap of the film is 1.6 eV. Electrical conductivity is high which is in the order of 10 -3 -10 -2 (9X cm) -1 .
