Consecutive to the interest in Graphene since its first isolation by mechanical exfoliation a decade ago, the broader family of two-dimensional (2D) materials has become the subject of extensive attention due to their atomic-scale thickness and unique properties, as well as the excitement ushered in by the announcement of the Nobel prize in Physics for the discovery of graphene. Meanwhile, we note an increased demand in nano-materials due to the development of industrial devices in quantum-computing, artificial intelligence, energy, bio-sensing, etc.
This talk aims to introduce the thermal transport properties of 2D materials’ and their Moiré patterns, along with 2D materials’ engineering applications. Systematic experimental and theoretical studies on thermal-transport properties of 2D materials will be introduced. It enables comparisons of experiment results between different conditions of 2D materials and discoveries of the interfacial thermal transport phenomena in h-Boron Nitride (hBN) encapsulated nano-structure. It has been found that the hBN fully encapsulated structure offers a great heat dissipation in nano-structure. Dr. Zhang and co-workers are also investigating the manipulation of energy transport by mechanical
deformation and Moiré angle, and energy conversion properties such as piezoelectric and thermoelectric effect. This work sheds light on engineering high-performance 2D field effect transistors, and facilitates the design of devices with controllable properties. In addition, our ongoing efforts in bio-sensing applications and the related scalable nano-manufacturing techniques of creating hundreds of field effect transistors around one single nano-wire at arbitrary positions will be introduced. These techniques have the engineering applications to bio-sensors, fluid sensors, gas filters, nano-robots, etc.
Dr. Xian (Annie) Zhang is an Assistant Professor at Stevens Institute of Technology Mechanical Engineering in August 2018 after assistant professorship at University at Buffalo (MDI) during which her work focused on developing 2D thermal heterostructures for various device applications. Prior to that Dr. Zhang obtained her Ph.D. in Mechanical Engineering from Columbia University, followed by research fellow experience at Columbia University/Cornell University. Her thesis work focused on experimental and theoretical study of nanomaterials (carbon nanotubes and two-dimensional transition metal dichalcogenides). She received her B.S. in Mechanical Engineering with highest honor from Shanghai Jiao Tong University, joint program with University of Michigan, in 2009.
