“…The (040) surface in SnS is the lowest energy surface [56] and, therefore, favored by kinetically limited growth conditions, such as lower temperatures and sufficiently long diffusion lengths. These low energy surfaces are bonded by van der Waals forces, and an orientation parallel to the substrate surface is favored by corresponding substrates, as previously reported [57]. On transition metals like molybdenum, covalent edge bonding is favored, resulting in (040) planes perpendicular and (101) surface parallel to the substrate surface, which results in the formation of plates growing out of the substrate plane [58].…”

Vapor Phase Synthesis of SnS Facilitated by Ligand-Driven “Launch Vehicle” Effect in Tin Precursors

Extraordinary low-temperature vapor-phase synthesis of SnS thin films from single molecular precursors is attractive over conventional high-temperature solid-state methods. Molecular-level processing of functional materials is accompanied by several intrinsic advantages such as precise control over stoichiometry, phase selective synthesis, and uniform substrate coverage. We report here on the synthesis of a new heteroleptic molecular precursor containing (i) a thiolate ligand forming a direct Sn-S bond, and (ii) a chelating O^N^N-donor ligand introducing a “launch vehicle”-effect into the synthesized compound, thus remarkably increasing its volatility. The newly synthesized tin compound [Sn(SBut)(tfb-dmeda)] 1 was characterized by single-crystal X-ray diffraction analysis that verified the desired Sn:S ratio in the molecule, which was demonstrated in the direct conversion of the molecular complex into SnS thin films. The multi-nuclei (1H, 13C, 19F, and 119Sn) and variable-temperature 1D and 2D NMR studies indicate retention of the overall solid-state structure of 1 in the solution and suggest the presence of a dynamic conformational equilibrium. The fragmentation behavior of 1 was analyzed by mass spectrometry and compared with those of homoleptic tin tertiary butyl thiolates [Sn(SBut)2] and [Sn(SBut)4]. The precursor 1 was then used to deposit SnS thin films on different substrates (FTO, Mo-coated soda-lime glass) by CVD and film growth rates at different temperatures (300–450 °C) and times (15–60 min), film thickness, crystalline quality, and surface morphology were investigated.

“…Films deposited onto ITO and Mo-coated glass are denser and more compact than those deposited on bare glass. N. Revathi et al found the same result using PVD technique to grow SnS onto different surfaces [17]. The composition of sprayed SnS thin films was estimated by Energy Dispersive X-Ray Spectroscopy (EDS).…”

The present paper reports on Tin Monosulphide (SnS) thin films elaborated by the Chemical Spray Pyrolysis (CSP) technique onto various substrates as simple glass, ITO-and Mo-coated glass in order to study the influence of substrates on the physical and chemical properties of SnS thin films. The structural analysis revealed that all films are crystallized in orthorhombic structure with (111) as the sole preferential direction without secondary phases. In addition, films prepared onto pure glass exhibits better crystallization compared to films deposited onto coated-glass substrates. Raman spectroscopy analysis confirms the results obtained from XRD with modes corresponding well to SnS single crystal orthorhombic ones (47, 65, 94, 160, 186, and 219 cm -1 ) without any additional parasite secondary phase like Sn 2 S 3 or SnS 2 . FESEM revealed that all films have cornflake like particles surface morphology and EDS analysis showed the presence of sulphur and tin with nearly stoichiometric ratio in films deposited onto pure glass. High surface roughness and large grains have been observed in film deposited onto glass. From optical spectroscopy it is inferred that band gap energy of SnS/glass and SnS/ITO were 1.64 eV and 1.82 eV, respectively.2

“…However, under illumination of the surface of deposited SnS, we observe an important cathodic photocurrent compared with that in the dark; suggests the existence of minority carriers (electrons), promotes the reduction of water producing H 2 gas [45] at the semiconductor/ electrolyte interface [1]. The cathodic photocurrent generation represents the typical behavior of p-type semiconductor conductivity with holes as the majority carriers [46,47]. SnS films deposited on ITO substrates showed the highest photoresponse compared to that obtained by Zainal [37] and Yongli [47].…”

“…Recently, use of photovoltaic solar cells leads to the research of new semiconducting thin films with acceptable efficiency. Metal chalcogenides are the most extensively studied ones such as tin sulfide [3][4][5][6][7][8][9][10][11][12][13]. This is one of the important IV-VI group semiconductors.…”

“…In recent years, SnS films have attracted more considerable attention as low toxicity and costeffective materials [3][4][5][6]. SnS has been used in photovoltaic conversion, halographic recording media, photoconductors, near infrared detector and solar control device [7][8][9][10]. SnS films have large optical absorption coefficient (α >10 4 cm -1 ) which is higher than GaAs and CdTe films and a high photoelectric conversion efficiency can be up to 25% [3,11].…”

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
