The advent of low-dimensional nanostructures has enabled a plethora of new devices and systems. Among them, nanoelectromechanical systems (NEMS) offers the unique capability of coupling the exquisite material properties found in these atomically-defined nanostructures with their mechanical degree of freedom, opening new opportunities for exploring exotic phenomena at the nanoscale. In this talk I will discuss three such examples: 1) using an individual carbon nanotube as a nanoscale balance to study low-dimensional phase transition, and 2) using multimode resonance in black phosphorus NEMS resonator to resolve the intrinsic anisotropy in these nanoscale crystals, and 3) exploring noise, nonlinearity, and dynamic range in 2D NEMS systems.
纳米机电器件，顾名思义，是具有机械运动自由度的纳米电子器件。此能动性使得这类器件在研究低维及纳米尺度的物理现象中具有一些独到的潜力和优势，例如研究纳米材料中的力学各项异性效应、纳米尺度上的力学非线性效应，以及动态和静态外力作用对纳米材料物理性质的调制。在这些工作中，低维纳米材料的机械运动和形变被用来帮助探索新的低维现象和纳米材料体系，帮助研究者“动”察秋毫：观察到一些原来不容易被测量的现象，进而带来新的发现。
BIOGRAPHY
Max Zenghui Wang is currently a professor in the Institute of Frontier and Fundamental Sciences (IFFS) at the University of Electronic Science and Technology of China (UESTC) and a visiting professor in the Electrical Engineering and Computer Science Department (EECS) at Case Western Reserve University (CWRU), where he had worked as a Research Associate (2012-2014) and Senior Research Associate and Investigator (2014-2016). His research interests and expertise primarily focus on nanoscale devices and systems, particularly Nanoscale Resonators, and High-Frequency Resonant Sensors & Transducers. Prior to joining Case, during 2010-2012, he worked at Cornell University as a postdoc researcher. He earned a Ph.D. degree (2010) from University of Washington, Seattle, for building an ultra-high frequency NEMS resonant sensor with an individual single-walled carbon nanotube, and using it to detect and study the low-dimensional phase transitions of the atomic layer adsorbed on the nanotube surface. He is an expert on studies of emerging nanoscale devices and sensors based on new materials such as carbon nanotubes, graphene, and other low-dimensional nanomaterials, and has published 20+ research articles in peer-reviewed journals, including Science, Nature Physics, Nature Nanotechnology, Nature Communications, Science Advances, Nano Letters, ACS Nano, Physical Review Letters, 2D Materials, etc.,. He has given dozens of invited talks and seminars at peer-reviewed conferences and research universities. He is an Associate Editor for Micro and Nano Letters, and has been serving on the Technical Program Committees for IEEE IFCS, IEEE Nano, and the MEMS/NEMS Technical Group at the American Vacuum Society (AVS) International Symposium and Exhibition.
