摘　　要：分别介绍了激子的基本概念及过渡金属硫族化合物(transition metal dichalcogenides,TMD)材料中不同类型的激子态,并对TMD材料中激子的调控方法和手段进行了系统综述;总结了TMD材料中激子问题的潜在研究方向及应用.The basic concepts of excitons and exciton complexes in TMD materials are discussed in this work,including bright and dark excitons,neutral and charged excitons,intralayer and interlayer excitons,and others.Further,methods are reviewed,of manipulating and tuning exciton complexes in TMD materials through strain,electrical and magnetic field,interlayer twist between neighboring layers.Finally,future research directions and applications of excitonic device are discussed.
