High-Pressure Synthesis of Single-Crystalline SnS Nanoribbons

Abstract

Two-dimensional tin monosulfide (SnS) is attractive for the development of electronic and optoelectronic devices with anisotropic characteristics. However, its shape-controlled synthesis with an atomic thickness and high quality remains challenging. Here, we show that highly crystalline SnS nanoribbons can be produced via high-pressure (0.5 GPa) and thermal treatment (400 °C). These SnS nanoribbons have a length of several tens of micrometers and a thickness down to 5.8 nm, giving an average aspect ratio of ∼30.6. The crystal orientation along the zigzag direction and the in-plane structural anisotropy of the SnS nanoribbons are identified by transmission electron microscopy and polarized Raman spectroscopy, respectively. An ionic liquid-gated fieldeffect transistor fabricated using the SnS nanoribbon exhibits an on/off current ratio of >10 3 and a field-effect mobility of ∼0.7 cm 2 V −1 s −1 . This work provides a unique way to achieve one-dimensional growth of SnS.

“…Additionally, SnS has a large specific surface area, strong carrier capacity, and its bandgap and electronic properties can be controlled through nanoparticle doping [ 23 ]. These characteristics endow SnS with significant potential in optoelectronic devices, electrochemical sensors, and friction nanogenerators [ 25 , 26 , 27 , 28 ]. However, the development and application of SnS in existing research on two-dimensional materials have been limited, which led to the motivation for this study.…”

Water-Based Bi2S3 Nano-Inks Obtained with Surfactant-Assisted Liquid Phase Exfoliation and Their Direct Processing into Thin Films

“…Metal chalcogenides cover a large family of 2D materials, which have gained recent attention due to their potential significance in many technological applications [1][2][3][4][5][6]. Among them, Bi 2 S 3 emerges as a potential candidate in thermoelectric applications, energy harvesting, biomedicine, sensors and optoelectronics, due to its low thermal conductivity, strong spin-orbit coupling, direct band structure and high absorption coefficient [7][8][9][10][11][12].…”
