Résumé     
We report here on the deposition of GaV4S8 thin layers by radio frequency (RF) magnetron sputtering in pure argon using a GaV4S8 target synthesized by spark plasma sintering. Thin layers were deposited at low deposition pressure and RF power, respectively 5.33 Pa and 60 W (i.e. 3 W cm(-2)). Since as-deposited thin layers were sulfur-poor and amorphous, a one hour ex-situ annealing at 873 K in a sulfur-rich atmosphere was performed to restore the stoichiometric composition GaV4S8 and the expected crystalline structure. Chemical analyses and high resolution transmission electron microscopy observations of thin layers are consistent with a GaV4S8 phase without any secondary phase. Rietveld refinements of the X-ray diffraction (XRD) patterns confirm the good crystalline quality of the annealed deposited film constituted of crystallites exhibiting an average grain size in the 32-36 nm range. Moreover, an excellent agreement was obtained between Rietveld refinement performed on GaV4S8 powder and thin films XRD data. (C) 2012 Elsevier B.V. All rights reserved.
