摘 要：Recent times have seen a surge of activity in the exploration of two dimensional atomic layered structures with a range of properties. Here we will discuss our recent efforts in exploring various two-dimensional materials including graphene, hexagonal boron nitride (h-BN), various dichalcogenide systems and hybrid atomic layers consisting of multiple compositions. Scalable synthesis through vapour deposition of several of these structures will be discussed. Understanding of defects such as grain boundaries, edges and point defects in these structures is important for manipulating physical properties in these materials. Our efforts in manipulating these layers into creating vertically stacked hybrids as well as laterally engineered layers will be described. Overall, the talk will summarize our recent progress in synthesizing and characterizing atomically engineered layers of materials with a wide range of properties and their applications on active nano-systems and high performance energy components, e.g. resonators, photodetectors, high-density capacitors, ultrafast lithium storage etc.

个人简介：Dr. Zheng Liu received his B.S. degrees (2005) at Nankai University (China), and completed his Ph.D at National Center for Nanoscience and Technology (NCNST, China), working on the synthesis and energy harvest of carbon nanotubes. He then worked in Prof. Pulickel M. Ajayan and Prof. Jun Lou’s groups as a joint postdoc research fellow (2010~2012) and research scientist (2012~2013) at Rice University (USA), focusing on the synthesis and applications of two-dimensional (2D) crystals, including graphene, hexagonal boron nitride, oxides and transition metal dichalcogenides (TMD: MoS2, MoSe2 etc). As a young pioneer in 2D materials research, he has made great contributions not only the synthesis of 2D heterostructures such as vertical and lateral graphene/h-BN, but also the 2D materials based nanoelectronics, active nano-systems and high performance energy components, e.g. resonators, graphene photodetectors, high-density capacitors, ultrafast lithium storage.
