| 1 | Tunable Schottky barrier width and enormously enhanced photoresponsivity in Sb doped SnS2 monolayer显示文摘Doping, which is the intentional introducti on of impurities into a material, can improve the metal-semiconductor interface by reducing Schottky barrier width. Here, we prese nt high-quality two-dime nsional SnS2 nano sheets with well-controlled Sb dopi ng concen tration via direct vapor growth approach and following micromechanical cleavage process. X-ray photoelectro n spectroscopy (XPS) measureme nt dem on strates that Sb contents of the doped samples are approximately 0.22%, 0.34% and 1.21%, respectively, and doping in duces the upward shift of the Fermi level with respect to the pristi ne SnS2. Tran smissio n electro n microscopy (TEM) characterizatio n exhibits that Sb-doped SnS2 nano sheets have a high-quality hexagonal symmetry structure and Sb element is uniformly distributed in the nano sheets. The phototra nsistors based on the Sb-doped SnS2 mono layers show n-type behavior with high mobility which is one order of magn itude higher than that of pristi ne SnS2 phototra nsistors. The photorespo nsivity and exter nal quantum efficiency (EQE) of Sb-S nS2 mono layers phototra nsistors are approximately three orders of magnitude higher than that of pristine SnS2 phototransistor. The results suggest that the method of reducing Shottky barrier width to achieve high mobility and photoresp on sivity is effective, and Sb-doped SnS2 mono layer has significant potential in future nanoelectronic and optoelectronic applications. | Junchi Liu Xiao Liu Zhuojun Chen Lili Miao Xingqiang Liu Bo Li Liming Tang Keqiu Chen Yuan Liu Jingbo Li Zhongming Wei Xidong Duan | 2019 | Nano Research2019，12，2： | 7 |
| 2 | Composite solid electrolyte of Na3PS4-PEO for all-solid-state SnS2/Na batteries with excellent interfacial compatibility between electrolyte and Na metal显示文摘High ionic conductivity and superior interfacial stability of solid electrolytes at the electrodes are crucial factors for high-performance all-solid-state sodium batteries. Herein, a composite solid electrolyte Na3PS4-polyethylene oxide is synthesized by the solution-phase reaction method with an improved ionic conductivity up to 9.4 × 10-5 S/cm at room temperature. Moreover, polyethylene oxide polymer layer is wrapped homogeneously on the surface of Na3PS4 particles, which could effectively avoid the direct contact between Na3PS4 electrolyte and sodium metal, thus alleviate their side reactions. We demonstrate that all-solid-state battery SnS2/Na with the composite solid electrolyte Na3PS4-polyethylene oxide delivers an enhanced electrochemical performance with 230 m Ah/g after 40 cycles. | Xiaoyan Xu Yuanyuan Li Jun Cheng Guangmei Hou Xiangkun Nie Qing Ai Linna Dai Jinkui Feng Lijie Ci | 2020 | Journal of Energy Chemistry2020，29，2： | 7 |

| 16 | SnS_2 quantum dots: Facile synthesis, properties,and applications in ultraviolet photodetector显示文摘Tin sulfide quantum dots(SnS_2 QDs) are n-type wide band gap semiconductor. They exhibit a high optical absorption coefficient and strong photoconductive property in the ultraviolet and visible regions. Therefore, they have been found to have many potential applications, such as gas sensors, resistors, photodetectors, photocatalysts, and solar cells. However, the existing preparation methods for SnS_2 QDs are complicated and require a high temperature and high pressure environments; hence they are unsuitable for large-scale industrial production. An effective method for the preparation of monodispersed SnS_2 QDs at normal temperature and pressure will be discussed in this paper. The method is facile, green,and low-cost. In this work, the structure, morphology, optical, electrical, and photoelectric properties of SnS_2 QDs are studied. The synthesized SnS_2 QDs are homogeneous in size and exhibit good photoelectric performance. A photoelectric detector based on the SnS_2 QDs is fabricated and its J–V and C–V characteristics are also studied. The detector responds under λ = 365 nm light irradiation and reverse bias voltage. Its detectivity approximately stabilizes at 1011 Jones at room temperature. These results show the possible use of SnS_2 QDs in photodetectors. | 李尧 唐利斌 李汝劼 项金钟 Kar Seng Teng 刘树平 | 2019 | Chinese Physics B2019，28，3： | 1 |

| 19 | In situ fabrication of 2D SnS2 nanosheets as a new electron transport layer for perovskite solar cells显示文摘To promote commercialization of perovskite solar cells (PSCs), low-temperatureprocessed electron transport layer (ETL) with high carrier mobility still needs tobe further developed. Here, we reported two-dimensional (2D) tin disulfide(SnS2) nanosheets as ETL in PSCs for the first time. The morphologies of the 2DSnS2 material can be easy controlled by the in situ synthesized method on theconductive fluorine-doped fin oxide (FTO) substrate. We achieved a championpower conversion efficiency (PCE) of 13.63%, with the short-circuit currentdensity (Jsc) of 23.70 mA/cm2 open-circuit voltage (Voc) of 0.95 V, and fill factor(FF) of 0.61. The high Jsc of PSCs results from effective electron collection ofthe 2D SnS2 nanosheets from perovskite layer and fast electron transport tothe FTO. The low Voc and FF are the results of the lower conduction band of 2DSnS2 (4.23 eV) than that of TiO2 (4.0 eV). These results demonstrate that 2Dmaterial is a promising candidate for ETL in PSCs. | Erling Zhao Liguo Gao Shuzhang Yang Likun Wang Junmei Cao Tingli Ma | 2018 | Nano Research2018，11，11： | 1 |
