内容摘要：The single atomic crystal layer of transition metal dichalcogenides (TMDCs), with numerous exotic physical properties, has become a worthy successor to graphene. Through the designed growth, it is possible to further realize the desired two-dimensional materials’ properties and addition functionalities. As examples, I will talk about manipulating the valley polarization of the single-layer MoS₂ grown on GaN substrate, large scale self-assembly of 1T’-2H MoTe₂ homojunctions by solid-to-solid phase transformation, and scaling of quantum Hall two-dimensional semiconductors.

报告人简介：Yu Ye is an assistant professor in School of Physics at Peking University. He received his Ph.D. degree in condensed matter physics from Peking University on 2012. Prior to joining PKU in July 2016, Yu was working as a postdoctoral researcher at University of California, Berkeley. His group (http://www.phy.pku.edu.cn/~yeyu/index.html) currently is interested in light-matter interactions and electrical transport properties in condensed matter physics, with an emphasis on novel physical phenomena emerging in atomically-thin materials, van der Waals heterostructures and surfaces/interfaces by nanoscale device designs, optical spectroscopy, electrical transport, and scanning photocurrent measurements.
