“…SnS film possesses narrow band gap, when thickness was ≈20-30 nm, the corresponding band gap should be around 1.40 eV (≈886 nm) due to quantum confinement effect. [48,49] This value is consistent with the obtained optimum excitation wavelength of 900 nm.…”

Group‐IV monochalcogenide ferroelectric materials possess fascinating nonlinear optical properties and electro‐optical effects which play a vital role in 2D ferroelectrics, multiferroics and nonlinear optoelectronics. However, the studies of nonlinear optical properties of group‐IV monochalcogenides are still in their infancy stage. Herein, the preparation of few‐layer SnS by the molecular beam epitaxy (MBE) method is reported and the efficient second harmonic generation (SHG) of SnS monochalcogenide is systematically scrutinized by using ultrafast nonlinear optical spectroscopy. The obtained thickness‐dependent SHG is highly related with the coherence length. Second‐order nonlinear susceptibility of few‐layer SnS is also obtained. Polarization‐dependent SHG studies reveal its intrinsic anisotropy pattern and can be utilized to identify the crystalline orientation of few‐layer SnS film.

“…Furthermore, the S precursor concentration can influence the morphology and phase formation of o-SnS films ( Figure 7 e). A higher TA concentration stimulates the formation of multi phases such as Sn 2 S 3 and Sn 3 S 4 (Sn 2 S 3 + SnS → Sn 3 S 4 ) [ 209 ] and a lower TA concentration assists the growth of single-phase o-SnS films, but with lower crystallinity [ 142 , 198 ]. A TA concentration of 0.1 M is preferable for the deposition of a single-phase, polycrystalline o-SnS with (101) preferred orientation [ 198 ], and a ST concentration of 0.75 M is advisable for (111)/(040) preferred orientation ( Figure 7 f).…”

The rapid research progress in tin-based binary sulfides (SnxSy = o-SnS, c-SnS, SnS2, and Sn2S3) by the solution process has opened a new path not only for photovoltaics to generate clean energy at ultra-low costs but also for photocatalytic and thermoelectric applications. Fascinated by their prosperous developments, a fundamental understanding of the SnxSy thin film growth with respect to the deposition parameters is necessary to enhance the film quality and device performance. Therefore, the present review article initially delivers all-inclusive information such as structural characteristics, optical characteristics, and electrical characteristics of SnxSy. Next, an overview of the chemical bath deposition of SnxSy thin films and the influence of each deposition parameter on the growth and physical properties of SnxSy are interestingly outlined.

“…Furthermore, there is a dearth of information in the literature regarding Na doping of SnS films and the impact of concomitant surfactant properties on the conductivity and surface morphology of such cells deposited on a metallic substrate like copper. While there are several reports on the chemical bath synthesis of SnS using similar chemical reagents [ 17 , 18 , 19 , 20 , 21 , 22 , 23 ], detailed investigations on the influence of temperature, composition, and surfactants on the conductivity of the SnS layer are lacking.…”

Thin films of tin (II) sulfide (SnS) were deposited onto a 500 µm thick copper substrate by a chemical bath method. The effect of sodium (Na) doping in these films was studied. The synthesis of the films was performed at temperatures of 60, 70, and 80 °C for 5 min. The microstructure of the SnS films analyzed by scanning electron microscopy (SEM) showed a compact morphology of the films deposited at 80 °C. The edges of the SnS grains were rounded off with the addition of a commercial surfactant. The thickness of different SnS layers deposited on the copper substrate was found to be 230 nm from spectroscopic ellipsometry and cross-section analysis using SEM. The deposition parameters such as temperature, surfactant addition, and sodium doping time did not affect the thickness of the layers. From the X-ray diffraction (XRD) analysis, the size of the SnS crystallites was found to be around 44 nm. Depending on the process conditions, Na doping affects the size of the crystallites in different ways. A study of the conductivity of SnS films provides a specific conductivity value of 0.3 S. The energy dispersive analysis of X-rays (EDAX) equipped with the SEM revealed the Sn:S stoichiometry of the film to be 1:1, which was confirmed by the X-ray photoelectron spectroscopy (XPS) analysis. The determined band-gap of SnS is equal to 1.27 eV and is in good agreement with the literature data.
