Two-dimensional materials: new opportunities for electronics,photonics and optoelectronics

<正>The exciting progress in graphene research in the past 15 years[1,2] has further stimulated the exploration of other non-graphene two-dimensional (2D) materials [3], such as h-BN [4,5], transitional metal dichalcogenides (TMDs)[6,7], black phosphorene [8],etc. Research on these ultimately atomic thin 2D materials has grown exponentially owning to their fascinating properties and enormous potential in the fields of physics, chemistry, optics and photonics, material sciences, medicine and engineering.
