报告题目New opportunities for surface science and sensor devices with two-dimensional materials and hybrids

报告时间:1 7日 (星期四 )上午10:00



The advent of two-dimensional (2D) materials (starting with graphene but also including many other layered “van der Waals” materials that may be reduced to several to single atomic layers) and composite/hybrid systems containing such materials has opened unprecedented new opportunities in surface science, materials physics, and nanotechnologies. Such 2D materials not only can be transferred to other substrates and surfaces to affect their physical and chemical processes, they can also act as flexible and transferrable 2D electronic or optical “sensing” layers whose properties sensitively depend on environments (ranging from substrates to external fields). Further, as the entire material becomes exposed surface with externally tunable properties, 2D materials can be used as versatile experimental platforms to enable concurrent, multi-modal materials characterizations and in-operando surface science measurements on functioning devices. This talk will discuss our representative research along these directions, fabricating such 2D materials and hybrids (involving graphene, as well as h-BN and topological insulators), developing new types of hybrid measurement techniques combining transport/devices with optical/Raman spectroscopy and scanning probe microscopy, and developing sensing platforms for radiation, chemical stimuli, electromagnetic fields and for studying other quantum materials and physics (such as novel magnetism and superconductivity).


Yong P. Chen is an internationally recognized experimental physicist who has worked on diverse quantum matters and devices involving systems such as graphene & 2D materials, topological insulators, cold atoms & molecules, exploring also their applications in electronics, spintronics, sensors, energy and quantum information. He received his BS and MS degrees in mathematics from Xi’an Jiaotong University and MIT. He received his PhD in Electrical Engineering, specializing in semiconductor physics and devices, from Princeton University, and did a postdoc in atomic physics and nanotechnology at Rice University. He started his independent research group in 2007 and joined the faculty at Purdue University, where he has become the Karl Lark Horovitz Professor of Physics and Astronomy and Professor of Electrical and Computer Engineering, and served as the Director of Purdue Quantum Science and Engineering Institute. He is also a Villum Investigator and Professor of Materials Physics at Aarhus University’s Institute for Physics and Astronomy and iNano Institute.  He has also been a principal investigator in WPI-AIMR International Research Center for Materials Sciences at Tohoku University and a specially appointed faculty member of Macau University of Science and Technology.  He has published over 200 papers (cited over 14000 times with h-index of 56) and delivered over 200 invited talks, and mentored over 30 PhD students and postdocs. He was a recipient of Horiba Award, NSF CAREER Award, DOD Young Investigator Award, IBM Faculty Award and an elected Fellow of American Physical Society (APS).
