Speaker：

Yuanbo Zhang received his Bachelor of Science degree from Peking University in 2000 and his PhD in Physics from Columbia University in 2006. He worked as a Miller Research Fellow at the University of California at Berkeley from September 2006 to June 2009 and as a postdoc research associate at IBM Almaden Research Center from March 2010 to September 2010. Since 2011, he has been a professor at Fudan University.

Yuanbo Zhang’s research interests include electronic transport in low-dimensional systems such as graphene, as well as scanning probe techniques and their application in studying low-dimensional nanostructures. Yuanbo Zhang is a New Cornerstone Investigator. He has been recognized for his work with several honors, including the Yeh Chi-Sun Prize in 2021, Tencent Xplorer Prize in 2020, and IUPAP Young Scientist Prize in 2010.

Abstract:

Since the discovery of graphene, 2D materials have emerged as a new class of materials that may impact future science and technology. While a few dozens of 2D materials have so far attracted most attention, the vast majority of the thousands of layered crystals remain largely unexplored. The large number of layered crystals, which cover all major branches of condensed matter physics, provide vast opportunities for exploring new physics in flatlands. In this talk I will discuss, through the lens of our own work, recent efforts in expanding the 2D material family that now includes ferromagnets, quantum anomalous Hall insulator, and high-temperature superconductors. Because the materials are now in the extreme 2D limit, it becomes possible to control their material properties with external means. I will discuss how the concept of gate modulation can be extended to 2D materials beyond semiconductors.
