As a new member in two-dimensional (2D) transition metal dichalcogenides (TMDCs) family, platinum diselenium (PtSe) has many excellent properties, such as the layer-dependent band gap, high carrier mobility, high photoelectrical coupling, broadband response, etc, thus it shows good promising application in room temperature photodetectors, broadband photodetectors, transistors and other fields. Furthermore, compared with other TMDCs, PtSeis chemical inert in ambient, showing nano-devices potential with higher performance and stability. However, up to now, the synthesis and its device applications are in its early stage. This review systematically summarized the state of the art of PtSefrom its structure, property, synthesis and potential application. Finally, the current challenges and future perspectives are outlined for the applications of 2D PtSe.
作为二维（2D）过渡金属二硫属化物（TMDCs）家族的新成员，二硒化铂（PtSe₂）具有许多优异的性能，如层依赖带隙、高载流子迁移率、高光电耦合、宽带响应等，因此在室温光电探测器、宽带光电探测器、晶体管等领域显示出良好的应用前景。此外，与其他TMDCs相比，PtSe₂在环境中化学惰性，显示出具有更高性能和稳定性的纳米器件潜力。然而，到目前为止，其合成及其器件应用尚处于早期阶段。本文综述系统总结了PtSe₂在结构、性质、合成及潜在应用方面的研究现状。最后，概述了二维PtSe₂应用当前面临的挑战和未来展望。
