Two‐dimensional (2D) transition metal dichalcogenides (TMDs) usually have poly‐phases, such as 2H, 3R and 1T. Controlling the structure phase of 2D TMDs is the key for engineering the physical and chemical properties of the materials and hence is vital to the applications. Many approaches, including doping/intercalation, alloying, defects, strain, electric field and so on, have been developed to tune the thermodynamic stability of the different phases of TMDs and then phase selective synthesis or controlled phase conversion has been achieved. More details are discussed in the article by Xie et al . on page 753–760.

二维（2D）过渡金属二硫化氢（TMD）通常具有多相，例如2H，3R和1T。控制2D TMD的结构阶段是设计材料物理和化学性质的关键，因此对应用至关重要。已经开发出许多方法，包括掺杂/嵌入，合金化，缺陷，应变，电场等，以调节TMDs不同相的热力学稳定性，然后实现了相选择合成或可控的相转化。Xie等人的文章中讨论了更多详细信息。在753–760页。
