Abstract

Two-dimensional materials offer unique opportunities to perform multimodal, “in-operando”, (nano)device-compatible measurements combining various surface science/optical microscopies and spectroscopies with electrical transport/gating, to gain a microscopic and deeper 
understanding of materials properties and device performance. This talk will describe several examples of such measurements in various gated 2D materials (including twisted/stacked heterostructures) ranging from graphene, 2D magnets and semiconductor transition metal 
dichalcogenides (TMDCs), studied by optical spectroscopy, angle resolved photoemission spectroscopy (ARPES), and scanning probe microscopies (SPM). In turn, multimodal measurements on 2D materials-based transistor devices help bring out a wide range of potential 
functionalities beyond electronic applications, ranging from photonics, spintronics, sensing and energy conversion.

Biography:

Prof. Yong P. Chen received a BSc degree in mathematics from Xi'an Jiaotong University and an MS degree in mathematics from MIT. He received his PhD in Electrical Engineering from Princeton University working with Nobel laureate Prof. Daniel C. Tsui. He then did a postdoc in physics and nanotechnology at Rice University before joining the faculty of Purdue University, where he became the Karl Lark-Horovitz Professor of Physics and Astronomy and Professor of Electrical & Computer Engineering, served as the Inaugural Director of Purdue 
Quantum Science and Engineering Institute, and co-founded/directed the first NSF IndustryUniversity-Cooperative-Research-Center (IUCRC) on Quantum Technologies. He is currently a Villum Investigator and Professor of Materials Physics at Aarhus University, Denmark and a 
principal investigator at Advanced Institute for Materials Research at Tohoku University, Japan, where he has been appointed an International Distinguished Professor. His group has made contributions to a wide range of quantum matters in both solid state and AMO physics, involving 
graphene, topological insulators, 2D materials, and cold atoms & molecules, and their potential applications. He is a Fellow of American Physical Society (APS) and American Association for the Advancement of Science (AAAS).
