摘要:

二维材料因其不同于体相的超薄原子结构、大的比表面积和量子限域效应等受到了人们的广泛关注。二维各向异性材料作为二维材料家族的一员, 其取向依赖的物理和化学性质, 使得对该类材料性能的选择性优化成为可能。过渡金属Re基硫属化合物作为各向异性材料的典型代表, 具有可调的可见光波段吸收带隙, 极弱的层间耦合作用力, 以及各向异性的光学、电学性能, 现已成为电子和光电子领域的研究热点之一。本文主要介绍了ReX2 (X=S, Se)的晶体结构和基本性质, 总结目前该材料体系主流的合成方法, 研究其各向异性物理特性及优化的手段和条件, 并对ReX2的制备和发展进行了展望。

Abstract:

Two dimensional (2D) materials have attracted wide attention due to their ultrathin atomic structure, large specific surface area and quantum confinement effect which are remarkably different from their bulk counterparts. Anisotropic materials are unique among reported 2D materials. Their orientation-dependent physical and chemical properties make it possible to selectively improve the performance of materials. As representative examples, Re-based transition metal dichalcogenides (Re-TMDs) have tunable bandgaps in visible spectrum, extremely weak interlayer coupling, and anisotropic properties in optics and electronics, which make them attractive in the application areas of electronics and optoelectronics. In this riviev, the unique crystal structures and intrinsic properties of the Re-based TMDs semiconductors are introduced firstly, and then the synthetic method is introduced, followed by discussion on the unique physical characterizations and optimized means. Finally, prospects and suggestions are put forward for the preparation and research of ReX2.
