Tellurium (Te) has a trigonal crystal lattice with inherent structural anisotropy. Te is multifunctional, e.g., semiconducting, photoconductive, thermoelectric, piezoelectric, etc., for applications in electronics, sensors, optoelectronics, and energy devices. Due to the inherent structural anisotropy, previously reported synthetic methods predominantly yield one-dimensional (1D) Te nanostructures. Much less is known about 2D Te nanostructures, their processing schemes, and their material properties. This review focuses on the synthesis and morphology control of emerging 2D tellurene and summarizes the latest developments in understanding the fundamental properties of monolayer and few-layer tellurene, as well as the recent advances in demonstrating prototypical tellurene devices. Finally, the prospects for future research and application opportunities as well as the accompanying challenges of 2D tellurene are summarized and highlighted.

Tellurene：其物理性质，可扩展的纳米制造和设备应用

碲（Te）具有固有的结构各向异性的三角晶格。Te是多功能的，例如半导体，光电导，热电，压电等。，用于电子，传感器，光电和能源设备。由于固有的结构各向异性，以前报道的合成方法主要产生一维（1D）Te纳米结构。人们对2D Te纳米结构，其加工方案及其材料特性知之甚少。这篇综述着重于新兴的2D碲化物的合成和形态控制，并总结了了解单层和少层碲化物的基本特性的最新进展，以及在演示原型碲化物设备方面的最新进展。最后，总结并强调了未来研究和应用机会的前景以及随之而来的2D碲烷的挑战。
