摘要

In recent years,two-dimensional (2D) layered metal dichalcogenides (MDCs) have received enormous attention on account of their excellent optoelectronic properties.Especially,various MDCs can be constructed into vertical/lateral heterostructures with many novel optical and electrical properties,exhibiting great potential for the application in photodetectors.Therefore,the batch production of 2D MDCs and their heterostructures is crucial for the practical application.Recently,the vapour phase methods have been proved to be dependable for growing large-scale MDCs and related heterostructures with high quality.In this paper,we summarize the latest progress about the synthesis of 2D MDCs and their heterostructures by vapour phase methods.Particular focus is paid to the control of influence factors during the vapour phase growth process.Furthermore,the application of MDCs and their heterostructures in photodetectors with outstanding performance is also outlined.Finally,the challenges and prospects for the future application are presented.
