“…The XRD 2θ-ω pattern and rocking curve of SnS grown at 270 °C was shown in previous work1. Only the diffractions from the family of SnS {002} planes were observed, suggesting that the SnS film stacks vertically on the mica substrate with a highly c-axis oriented direction.…”

“…However, the SnS films prepared by the methods above typically exhibit disordered growth orientations in addition to a polycrystalline structure, resulting in significant material defects arising from high concentration of pinholes and grain boundaries811. In this work, van der Waals (vdW) epitaxial growth by molecular beam epitaxy (MBE) technique was employed to produce high SnS films with high crystallinity which has strong impact on the electrical properties of the material12. High concentration of material defects will lead to the degradation of the electrical properties of the film and, thereby, severely affecting the application of the material in both optoelectronic and electronic devices1.…”

In this paper we report the growth of high quality SnS thin films with good crystallinity deposited on two-dimensional (2D) mica substrates. It is believed that the 2D nature of SnS, with strong intra-layer covalent bonds and weak inter-layer van der Waals interactions, is responsible for its relative insensitivity to lattice mismatch. We also investigated the reduction of Sn vacancies in the material using Sn-compensation technique during the material growth process. The experimental results clearly demonstrated substantial enhancements in the electrical and structural properties for films deposited using Sn-compensation technique. A mobility of 51 cm2 V−1 s−1 and an XRD rocking curve full width at half maximum of 0.07° were obtained. Sn-compensated SnS/GaN:Si heterojunctions were fabricated and significant improvement in both the I-V characteristics and the spectral responsivities of the devices were characterized.

“…The lattice constants are obtained as = 3.73Å, = 3.73Å, and = 9.37Å, respectively. Nano-TiO 2 in anatase phase, belonging to the wide band gap semiconductor materials [17][18][19], is extensively applied to the photocatalysis field, also because of its inexpensive, abundant, and nontoxic constituent elements [14,20,21]. It is obviously seen that the lower spectrum is a superposition of the upper and middle ones, implying the micrometer-or submicrometer-sized marble powder surface is sufficiently modified with the nano-TiO 2 .…”

We report a brand new recycling route of waste marble powder, by means of surface modification with homemade nano-TiO 2 particles to produce low cost coating materials for the application in air quality improvement. The as-prepared nano-TiO 2 in anatase phase exhibits excellent photocatalytic characteristic, reflected by the high degradation rate of over 95% of methylene blue within 6 hours of UV irradiation. The prepared coating consisting of nano-TiO 2 clad marble powder was tested by monitoring the decomposition rate of formaldehyde gas. A high degradation efficiency of about 95% within 9 hours of illumination is achieved, demonstrating a promising potential for removing the harmful and toxic organic pollutants in air while applying this coating in buildings both interiorly and exteriorly.

Layered SnSe is an emerging class of black phosphorus, which is non-toxic, eco-friendly, and chemically stable. Recently, SnSe nanostructures have triggered more research interest and enabled broad applications beyond demonstrating their great performances on thermoelectricity. However, there are also a great many significant studies of SnSe nanostructures beyond thermoelectricity. SnSe quantum dots, nanosheets, nanowires, and thin films with diverse morphologies have been synthesized using various chemical and physical preparation approaches. SnSe is a multi-phase semiconductor, and its nanostructures endow unique properties, including small electron effective mass, ultralow thermal conductivity, huge anisotropy, and the largest 2D piezoelectric coefficient ever predicted. The versatility of SnSe nanostructures can enable potential applications ranging from ultrafast photonics, logic devices, photodetectors, solar cells, photocatalysis, energy storage, and biology to more cutting-edge interdisciplinary subjects. In this review, the recent advances made in SnSe nanostructures are summarized, covering basics, synthesis, properties, and applications, just giving a passing comment on thermoelectricity. An in-depth perspective on the challenges and prospects of SnSe nanostructures toward broad and practical applications is also given.
