“…1. It was observed that at lower temperature (280ºC and 320ºC) the band gap was higher (1.8 eV and 1.78 eV) than generally reported 1.6 -1.75 eV for SnS film [10,11]. In addition, at higher temperature (440ºC) again high band gap (1.85 eV) was observed.…”

“…Oxygen and carbon peaks may cause from the surface contamination. 23 Sn 3d exhibits two distinct peaks belong to Sn 3d 5/2 and Sn 3d 3/2 that are detected at 487.38 eV and 495.82 eV, respectively ( Figure 2B). The difference between these two peaks is 8.44 eV which is in agreement with the literature.…”

“…The difference between these two peaks is 8.44 eV which is in agreement with the literature. 23,24 The binding energies of the Sn 3d 5/2 and Sn 3d 3/2 peaks cannot be related to the values of elemental Sn (0) ortin in other phases of Sn x S y , but can be assigned to Sn 2+.23 No secondary phases, for instance SnS 2 with the ionic state of Sn 4+ , were detected that is placed at the binding energy at 485.5 eV. 23,24 The peak located at 162.8 eV could be assigned to the binding energies of the S 2− of SnS ( Figure 2C).…”

Orthorombic tin (II) sulfide are synthesized by a simple and cost effective mechanochemical method in a high energy ball mill over different time scales. After the detailed characterization by X-ray photoelectron spectroscopy (XPS), X-ray diffraction, Fourier Transform Infrared (FTIR) spectroscopy, thermogravimetricanalysis (TGA), scanning electron microscopy (SEM) and EDX mapping, 2 hours milling time is found to be the optimum as anode in sodium-ion batteries. Later, electrochemical performances are investigated with regards to the binder type; sodium carboxy methyl cellulose (CMC), sodium alginic acid (Na-alginate) and polyvinylidene fluoride (PVdF), in which the best performances are obtained with Na-alginate. Comprehensive electrochemical impedance spectroscopy (EIS) measurements are pursued in order to examine the effect of binders. EIS tests of SnS anodes after Crate test reveal much bigger resistivity with PVdF binder than that of CMC and Na-alginate. Postmortem surface morphology analysis by means of SEMdemonstrates the self-healing properties of Na-alginate binder with no visible crack formation after cycles. As a whole, more than 300 mAh/g capacity is obtained over 60 cycle at C/5 current density without the help of carbon addition during the synthesis of the SnS composite.

“…SnS films have been deposited by various techniques such as atomic layer deposition [14], chemical bath deposition [15], hydrothermal method [16], mechanochemical route [17], silar method [18], spray pyrolysis [19], electron beam evaporation [20], sputtering [21], electrodeposition [1,12,22,23] and vacuum evaporation [4]. Among these techniques, electrodeposition is simple, inexpensive and convenient for large area deposition.…”

SnS films have been prepared by electrodeposition technique onto Cu and ITO substrates using acidic solutions containing tin chloride and sodium thiosulfate with sodium citrate as an additive. The effects of sodium citrate on the electrochemical behavior of electrolyte bath containing tin chloride and sodium thiosulfate were investigated by cyclic voltammetry and chronoamperometry techniques. Deposited films were characterized by XRD, FTIR, SEM, optical, photoelectrochemical, and electrical measurements. XRD data showed that deposited SnS with sodium citrate on both substrates were polycrystalline with orthorhombic structures and preferential orientations along (111) directions. However, SnS films with sodium citrate on Cu substrate exhibited a good crystalline structure if compared with that deposited on ITO substrates. FTIR results confirmed the presence of SnS films at peaks 1384 and 560 cm-1. SEM images revealed that SnS with sodium citrate on Cu substrate are well covered with a smooth and uniform surface morphology than deposited on ITO substrate. The direct band gap of the films is about 1.3 eV. p-type semiconductor conduction of SnS was confirmed by photoelectrochemical and Hall Effect measurements. Electrical properties of SnS films showed a low electrical resistivity of 30 Ω cm, carrier concentration of 2.6 × 10
