摘　　要：In recent years,two-dimensional(2D)materials have attracted extensive interests due to the large exciton binding energy different from bulk materials.Many peculiar properties have been discovered that have farreaching perspectives in the next generation of optoelectronic devices.In this review,we introduce the forms of exciton existence in 2D materials and several promising 2D materials with good applications at first.Then,we summarize relevant contemporary tools for probing exciton dynamics and methods of regulating 2D exciton transport,for instance,electrical regulation,stress/surface wave regulation and moirépotential regulation,etc.Finally,we conclude the general development of regulation in 2D materials and propose several possible opportunities of application prospect.
