Molecules are the fundamental building blocks of any materials. Creating functional devices at the molecular scale and understanding the underlying physics and chemistry hold promise for developing smaller, faster, and more efficient nanodevices for applications in optoelectronics, energy conversion, and chemical / bio-sensing.
In this talk, I will introduce my recent research in developing experimental tools to address challenges in probing and controlling charge and energy transport in molecular tunnel-junction devices. First, I will begin by showing how a single molecular diode and switch can be experimentally built and characterized (Nat Chem 2016). Second, I will introduce experimental observation of thermoelectric energy conversion at the molecular scale (Nat Nanotechnol 2018). Third, I will talk about our recent breakthrough in quantifying plasmonic hot carrier distribution via single molecule transport measurements (Science 2020).
Dr. Kun Wang is currently an Assistant Professor in Physics and Chemistry at Mississippi State University. He received his Ph.D. in Physics from the University of Georgia in 2016 under the guidance of Prof. Bingqian Xu. Prior to joining MSU, Dr. Wang worked as a Research Fellow in Prof. Pramod Reddy’s group at the University of Michigan, Ann Arbor. His research interest is in the development of experimental tools and methods to explore intriguing optoelectronics, quantum transport, and energy conversion phenomena at the nano and molecular scale.
