Mid-infrared and Terahertz Optoelectronics in 2D Materials

讲座内容：2D materials have attracted significant attention in thepast few years for photonic applications owing to its promising opticalproperties. In this talk, I am going to present our research research inapplying 2D materials for applications in the mid-infrared and Terahertzregimes, such as photodetectors, modulators and plasmonics. In particular, Iwill show the first demonstration of broadband graphene nanoribbonphotodetectors that covers from the visible to the mid-infrared with a highresponsivity; Terahertz broadband graphene modulator with a 100% modulationdepth and a high speed; and low damping rate graphene and topological insulatorplasmons.
