摘要

Two-dimensional (2D) atomic crystals, best exemplified by graphene, have emerged as a new class of material that may impact future science and technology. From a material physicist’s point of view, 2D materials provides vast opportunities on two fronts: First, the reduced dimensionality in these 2D crystals often leads to novel material properties that are different from those in the bulk; Second, the entire 2D crystal is a surface, so it is possible to have better control of their material properties with external perturbations. In this talk I will illustrate these two points with two examples: black phosphorus and 1T-TaS2. These two layered materials have vastly different properties. Black phosphorus is a 2D semiconductor, and its superior material quality has recently enabled us to observe the quantum Hall effect. 1T-TaS2, on the other hand, is a metal with a rich set of charge density wave phases. We explore their electronic properties while the doping and dimensionality of the 2D systems are modulated.

 

个人简介:



Yuanbo Zhang received his BS from Peking University in 2000 and his PhD in Physics from Columbia University in 2006. He was a Miller Research Fellow at the University of California at Berkeley from Sept. 2006 to Jun. 2009, a postdoc research associate at IBM Almaden Research Center from Mar. 2010 to Sept. 2010, and a professor of Fudan University from 2011. His main research interests are: Electronic transport in low-dimensional systems including graphene; Scanning probe techniques and their application in studying low-dimensional nanostructures. Major honors include: Charles Townes Fellowship, Columbia University (2005); Miller Fellow, University of California, Berkeley (2006); IUPAP Young Scientist Prize, International Union of Pure and Applied Physics (2010); Nishina Asia Award, Nishina Memorial Foundation, Japan (2014).
