Two-dimensional tin monosulfide (SnS) is attractive for the development of electronic and optoelectronic devices with anisotropic characteristics. However, its shape-controlled synthesis an atomic thickness high quality remains challenging. Here, we show that highly crystalline SnS nanoribbons can be produced via high-pressure (0.5 GPa) thermal treatment (400 °C). These have a length several tens micrometers down to 5.8 nm, giving average aspect ratio ∼30.6. The crystal orientation along zigzag direction in-plane structural anisotropy are identified by transmission electron microscopy polarized Raman spectroscopy, respectively. An ionic liquid-gated field-effect transistor fabricated using nanoribbon exhibits on/off current >103 mobility ∼0.7 cm2 V-1 s-1. This work provides unique way achieve one-dimensional growth SnS.

Abstract Local strain, as a small degree and single direction strain method, can effectively regulate the structures electronic properties of armchair Janus MoSSe nanoribbon, so that system be transformed from original 0.467 eV indirect band gap into 0.259 (3-zig), 0.117 (3-arm), 0.080 (6-arm) 0.139 (9-zig) direct band-gap semiconductor according to different degrees directions. Compared with traditional MoS 2 MoSe nanoribbons, nanoribbon shows relatively stable structure under local strain. The are anisotropic when is along Due broken mirror symmetry appearance in-plane polarization, spin polarization effect more remarkable. When C = 0.167 zigzag ⩾ 0.056 direction, exhibits half-metallic surprisingly induces magnetic moment. For total moment up 2.05 μ B 0.111. A method applied system, which geometric configuration without external doping, introduce magnetism, providing possibility for expanding nanoribbons potential nanoelectronic spintronic materials.
