Two-dimensional (2D) materials, including graphene, have extra-ordinary electrical, optical, and mechanical properties. Ultrahigh carrier mobility and broadband operation of 2D materials have attracted a grate attention from numerous device designers in data communication technology. Different from graphene having gapless energy structure, 2D transition metal dichalcogenides (TMDCs), including black phosphorus (BP), MoS2, ReS2, and WSe2, are semiconductors with energy bandgap of 1.57–2 eV. This characteristic have allowed us to develop specified novel light emitters, modulators, and photodetectors. In this talk, we present recent developments and perspectives on the 2D material-based opotoelectronic devices for ultra-high speed data communication technology. Hybrid structures based on van der Waals heterostructure are mainly focused, which are considered as an alternative candidates for substituting conventional semiconductor-based optoelectronics. |
