What is Carbon-doped Sb2S3 thin films: Structural, optical and electrical properties about?
We report the modification of electrical properties of chemical-bath-deposited antimony sulphide (Sb 2 S 3 ) thin films by thermal diffusion of carbon. Sb 2 S 3 thin films were obtained from a chemical bath containing SbCl 3 and Na 2 S 2 O 3 salts at room temperature (27 1C) on glass substrates. A carbon thin film was deposited on Sb 2 S 3 film by arc vacuum evaporation and the Sb 2 S 3 -C layer was subjected to heating at 300 1C in nitrogen atmosphere or in low vacuum for 30 min. The value of resistivity of Sb 2 S 3 thin films was substantially reduced from 10 8 O cm for undoped condition to 10 2 O cm for doped thin films. The doped films, Sb 2 S 3 :C, retained the orthogonal stibnite structure and the optical band gap energy in comparison with that of undoped Sb 2 S 3 thin films. By varying the carbon content (wt%) the electrical resistivity of Sb 2 S 3 can be controlled in order to make it suitable for various opto-electronic applications.
