With the development of preparation technology for thin-film materials and nanomaterials, SnSe/SnS has been successfully utilized in multiple fields, including photothermal, photoelectric and ferroelectric fields.

2023年2月14日 · In this work, we report the low-pressure PVD synthesis of high-quality 2D SnSe crystals with thinner thickness and larger lateral sizes. The as-synthesized SnSe displays high crystallinity and phase purity, as confirmed by Raman, X-ray photoemission spectroscopy (XPS), and scanning transmission electron ( (micro-scopy)) (STEM).

2024年10月16日 · We present a novel, straightforward, and reproducible one-pot heating up technique to synthesize core/crown SnSe/SnS nanosheets by a careful adjustment of the sulfur and selenium precursor reactivity. Here, the SnSe nanosheets are prepared via a wet-chemical route using SnCl 2 and selenium phosphines.

2022年10月17日 · Here, we develop a physical vapor deposition approach to synthesize two-dimensional p-doped SnSe. The local phase segregation of SnSe 2 microdomains and accompanying interfacial charge transfer...

SnSe crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two SnSe sheets oriented in the (0, 0, 1) direction. Sn2+ is bonded in a 5-coordinate geometry to three equivalent Se2- atoms. There are one shorter (2.78 Å) and two longer (2.84 Å) Sn–Se bond lengths.

2022年4月13日 · 二维SnSe/SnS薄膜因其制备简单、环保、无毒、成本低、光学和电学性能优异等特点，逐渐成为太阳能电池合适的光吸收材料。 根据Shockley-Queisser准则，SnSe/SnS基太阳能电池的极限效率分别达到32%和33%。

2018年1月8日 · The bandgap and optoelectronic properties of SnSe have been studied, which illustrate the potential of the ultrathin SnSe nanosheets (NSs) in photodetector and photovoltaic fields. 27 SnS is similar to SnSe for they both have narrow bandgaps and SnS is excellent for the application in thin-film solar cells because of its optical bandgap of 1.3 ...

2020年9月4日 · Using high-resolution inelastic neutron scattering (INS) on single-crystals, we chart the evolution of phonons in SnS from 150 K to 1050 K and clearly reveal the soft-mode nature of the Pnma–Cmcm...
