Title: A Vibrant New World—Exploring New Physics and Materials with Nanoelectromechanical Systems (NEMS)

Abstract：

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 two such examples: 1) using an individual carbon nanotube as a nanoscale balance to study low-dimensional phase transition, 2) using multimode resonance in black phosphorus NEMS resonator to resolve the intrinsic anisotropy in these nanoscale crystals, and 3) studying Brownian resonance and nonlinear motion in MoS₂ NEMS.
