个人简介

    谢弘超，2019年8月于美国宾夕法尼亚州立大学获得博士学位，随后在美国密西根大学从事博士后研究工作，2022年10月加入华南理工大学，担任准聘教授。主要研究方向为：（1）二维磁性及其在纳机电系统的应用；（2）二维莫尔超晶格与器件系统。在二维自旋、谷赝自旋激子的样品制备、物态表征及调控方面取得系列创新成果。以第一作者（含共一）身份在Nature Physics, Nature Materials和Nano Letters等国际知名期刊上发表研究工作，共计发表SCI论文十余篇。

      Dr. Hongchao Xie got his Ph.D. degree from The Pennsylvania State University in August 2019, and then worked in The University of Michigan, Ann Arbor for three years as a postdoctoral research fellow. Dr. Xie has joined South China University of Technology as a tenured track associate professor since October 2022. His research interest mainly lies in experimentally exploring (1) 2D magnetism and its applications on nanoelectromechanical systems (NEMS), (2) 2D moiré superlattices and device systems, (3) 2D twist multilayer systems and their electronic/magnetic states of matter. He has realized series of remarkable progress in developing twist and suspended devices of 2D spin, 2D exciton with valley pseudo-spin and the characterization . He has published research work as first (co-first) author in high-profile journals such as Nature Physics, Nature Materials and Nano Letters, with more than 10 SCI papers peer-reviewed in total.
