Abstract Details: The 2D materials family keeps its amazing pace in expanding its family size, with more and more growing and outreaching branches in its family tree. Each member in this family has its uniqueness in both fabrication methods and intriguing properties. Many of the layered materials also share clear commonalities, most notably weak van der Waals (vdW) coupling between the layers. In this talk, we will review some of the latest developments in exploration of the atomistic growth mechanisms of several newcomers to the 2D materials family, including blue phosphorene, grown on metal or semiconductor substrates following a novel half-layer-by-half-layer mode, tellurene, whose formation mechanism is rooted in the multi-valency nature of Te, and an unexpected layered material potentially harboring high-Tc superconductivity. Time permitting, we also present some of our latest findings towards materialization of 2D topological superconductivity that may serve as superior platforms for detecting and braiding Majorana zero modes.

About the Speaker: Prof. Zhenyu Zhang received his B.S. degree from Wuhan University in 1982 and PhD degree from Rutgers University in 1989, both in physics. He was a Distinguished Research Scientist in the Materials Science & Technology Division of Oak Ridge National Laboratory and Professor of Physics (Chair of Excellence) at the University of Tennessee, USA before joining USTC in January 2011. Since 2011, he has been a Distinguished Chair Professor at USTC and serves as co-founding Director of the International Center for Quantum Design of Functional Materials (ICQD). His research interests lie in the fields of theoretical understanding of the formation, stability, properties, and potential applications of low-dimensional materials. His most recent research emphases have been on quantum design of functional materials for clean energy and quantum information. He has authored/coauthored ~270 peer-reviewed papers, and has disseminated the research findings in over 280 invited/keynote/plenary talks and lectures at professional meetings and research institutions. He is a fellow of the American Physical Society, and has served or currently serves on the editorial boards of several professional journals.
