Thin films of SnS have been deposited on conducting glass substrates using spray pyrolysis. The spray solution consisted of tin chloride and thiourea dissolved in a mixture of isopropyl alcohol and water. The substrate temperature was varied in the range, 100-450°C. The films formed at growth temperatures between 300°C and 360°C were polycrystalline, single phase and nearly stoichiometric with a strong {1 1 1} preferential orientation. These films were p-conductivity type with an electrical resistivity of 30 Ω cm and a net carrier concentration of 1.2 × 1015 cm-3. These layers had a direct band gap of 1.32 eV. The films deposited at temperatures <300°C and >360°C deviated from stoichiometry with other chemical phases present.
