“…Other relevant applications in solar cell devices have been extensively studied . SnS is amphoteric and can be used as an absorber layer in solar cells, and its optical absorption coefficient is α > 104 cm −1 . Moreover, SnS has a narrow direct optical band gap of 1.3 eV, near the optimum gap for photovoltaic solar energy conversion .…”

for exploring 2D materials. In the past decade, studies have been extensively reported [2] on diverse optical devices such as absorbers, modulators, detectors, etc. Liu et al. [3] experimentally demonstrated a broadband, high-speed and waveguideintegrated electroabsorption modulator based on monolayer graphene. Vicarelli et al. [4] applied graphene field-effect transistors as room-temperature terahertz detectors. In addition, light/graphene interactions have also been extensively investigated, and graphene shows saturation of the optical absorption, THz emission, SHG under symmetry breakage, and third-order nonlinear refraction. The nonlinear refractive index (n 2 ) and third-order nonlinear susceptibility (χ (3) ) in graphene have been experimentally investigated by four-wave mixing and Z-scan measurements. [5] Furthermore, another measurement technique based on spatial self-phase modulation (SSPM) has been employed to analyze the nonlinear optical responses of different types of nanomaterials. In 2011, Wu et al. investigated the third-order nonlinear susceptibility in chemically exfoliated graphene nanosheets using the SSPM method. [6] Since the discovery of single-layer graphene, much effort has been devoted toward finding new 2D nonlinear optical materials As an analogue compound of black phosphorus, a new 2D semiconducting few-layer SnS is successfully synthesized, and its nonlinear optical response is investigated. It is shown that its nonlinear refractive index and third-order nonlinear susceptibility are measured as n 2 ≈ 10 −5 (cm 2 W −1 ) and monolayer (3) χ χ ≈ 10 −10 (e.s.u.), respectively. By taking advantage of such a large Kerr nonlinearity, an all-optical switching technique based on few-layer SnS is realized through modulating the propagation of the signal beam by another controlling beam. The achievement of all-optical switching indicates that few-layer SnS could be developed as an excellent optical material for alloptical signal processing. More importantly, a conceptually new and reliable information conversion system based on spatial cross-phase modulation in few-layer SnS, that is, the transmission and conversion of a sequence of bit information from one wavelength channel to the other, is presented. The contributions reveal potential applications of few-layer SnS as a new type of optical information material, and it is therefore anticipated that SnS and other IV-VI compound-based 2D nanomaterials could find promising applications in photonic devices such as optical modulators, optical switches, detectors, etc.

“…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.…”

“…The concentration of the complexing agent similarly influences the morphological and optical properties of the o-SnS, c-SnS, and SnS 2 films. The direct optical energy gap for o-SnS films reduces with increasing complexing agent concentration (TSC, 0.06–0.08 M; TEA, 12.5–13 M; TTA, 0.6–1.4 M) from 2.16 eV to 1.17 eV [ 50 , 182 , 214 ], but rises from 1.67 eV to 1.73 eV [ 26 ] for c-SnS films with EDTA (0.075–0.125 M) ( Figure 7 l). The change in complexing agent concentration (TSC, TTA) improves the compactness and morphology of o-SnS films ( Figure 7 m).…”

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.
