Published: December 2023

Tin selenide (SnSe) holds great potential for abundant future applications, due to its exceptional properties and distinctive layered structure, which can be modified using a variety of techniques. One of the many tuning techniques is pressure manipulating using the diamond anvil cell (DAC), which is a very efficient in situ and reversible approach for modulating the structure and physical properties of SnSe. We briefly summarize the advantages and challenges of experimental study using DAC in this review, then introduce the recent progress and achievements of the pressure-induced structure and performance of SnSe, especially including the influence of pressure on its crystal structure and optical, electronic, and thermoelectric properties. The overall goal of the review is to better understand the mechanics underlying pressure-induced phase transitions and to offer suggestions for properly designing a structural pattern to achieve or enhanced novel properties.

Tin (Sn)-based two-dimensional (2D) materials exhibit intriguing mechanical and optoelectrical properties owing to their non-centrosymmetric crystallinity and tunable band structures. A judicious integration of these individually decoupled properties is projected to introduce unparalleled functionalities into them, which remain largely unexplored. Herein, we develop wafer-scale tin selenide (SnSe, 0 < < 1) 2D layers composed of thermodynamically stable coexisting phases of SnSe and SnSe with distinct functionalities and identify a strong interplay between their mechanical and optoelectrical characteristics.

2D-layered materials are recognized as up-and-coming candidates to overcome the intrinsic physical limitation of silicon-based devices. Herein, the coexistence of positive persistent photoconductivity (PPPC) and negative persistent photoconductivity (NPPC) in SnSe thin films prepared by pulsed laser deposition provides an excellent avenue for engineering novel devices. It is determined that surface oxygen is co-regulated by physisorption and chemisorption, and the NPPC is attributed to the photo-controllable oxygen desorption behavior.

Controlled synthesis of hierarchical flowerlike cobalt tin sulfide (SnCoS) is successfully obtained using the chelation of the biomolecule l-asparagine with cobalt-tin metal cations by a hydrothermal technique. l-asparagine plays a crucial role as an inducer and a good structure-directing activity. Subsequently, pine needle-shaped cobalt iron selenium (FeCoSe) is tightly deposited on the SnCoS surface to construct cobalt tin sulfide coated with cobalt iron selenide (FeCoSe@SnCoS) heterostructure, which has exposed more active sites and the most abundant channels for electron/ion transfer.

Macroscopic Monochalcogenide van der Waals Ferroics: Growth, Domain Structures, and Curie Temperature.

Two-dimensional and layered van der Waals materials promise to overcome the limitations of conventional ferroelectrics in terms of miniaturization and material integration, but synthesis has produced only small (up to few micrometer-sized) ferroic crystals. Here, we report the realization of in-plane ferroelectric few-layer crystals of the monochalcogenides tin(II) sulfide and selenide (SnS, SnSe) whose linear dimensions exceed the current state of the art by up to 1 order of magnitude. Such large crystals allow the investigation of ferroic domain patterns that are unaffected by edges and finite-size effects.

Thermoelectric technology experienced rapid development over the past 20 years, with the most promising applications being in both power generation and active cooling. Among existing thermoelectrics, tin selenide (SnSe) has had particularly rapid development owing to the unexpectedly high thermoelectric efficiency that has been continuously established over the past decade. Several transport mechanisms and strategies used to interpret and improve the thermoelectric performance of SnSe have been important for understanding and developing other material systems with SnSe-like characteristics.
