title = "Chemistry of δ-SnS: New tin monosulflde polymorph thin films from galvanostatic electrodeposition",
abstract = "Galvanostatic deposition of tin monosulfide thin films (δ-SnS phase) on transparent conductive glass was studied. Uniform films were deposited in aqueous baths with tartaric acid. Cyclic voltammetry suggested tin-tartrate complexes were crucial to film electrodeposition, suppressing tin metal reduction in favor of sulfur species reduction. X-ray diffraction showed primitive orthorhombic symmetry for δ-SnS (a = 11.380 {\AA}, b= 4.029 {\AA}, c = 4.837 {\AA}). δ-SnS was converted to α-SnS (a = 11.172 {\AA}, b = 3.994 {\AA} c = 4.311 {\AA}) following annealing at ∼ 270 °C in Ar(g). Characterizations of the as-deposited films confirmed 1:1 Sn/S. The δ-SnS structure was consistent over a range of deposition temperatures (50, 70, and 90 °C). UV/Vis spectrometry confirmed increased disorder in films deposited at 50 °C. A direct allowed optical band gap transition of lower energy for the δ-SnS phase (1.05 eV) was obtained compared to that for α-SnS (direct, 1.2 eV).",
