Among various two-dimensional (2D) materials, graphene has brought a great deal of excitement to our community with its attractive and unique properties. Such excellent characteristics have led many researches on other 2D materials, such as hexagonal boron nitride (hBN), molybdenum disulfide (MoS2), tungsten diselenide (WSe2) and so on. Recently, van der Waals heterostructures (vdWH) have been achieved by putting 2D materials onto another, in the similar way to build Lego blocks. This enables us to investigate physical properties of atomically-sharp heterostructure interfaces and fabricate high performance optoelectronic devices for advanced applications. In this talk, effect of defects on electrical, optical, and mechanical properties of various 2D materials will be shortly discussed. Then, high performance electronic/optic devices based on vdWH of 2D materials will be introduced for various applications, such as transistors, memories, and solar cells. |
