Research Interests

Molecules, the fundamental building blocks of matter, are full of amazing chemistry and physics. A functional device made of a single molecule or nanoscale assemblies of molecules not only represents the ultimate device miniaturization, it also holds promise for addressing grand challenges in optoelectronics, computing, energy conversion, and nano-sensing.

Our research focuses on probing charge transport, energy conversion, catalysis, and sensing at the molecular scale, and further engineering the role of molecular building blocks in various nanoscale systems. Specifically, we leverage scanning probe-based techniques in conjunction with other advanced nano-measurement tools to study the transport properties of molecular materials and nanostructures (including single molecules, molecular monolayers/thin films, and molecular assemblies/networks), and how their properties respond to different external stimuli (light, heat, electrochemical environment, mechanical modulation and magnetic field). Our experiments will shed light on the fundamental physical and chemical mechanisms that govern the behavior of molecules in nanoscale devices and establish the correlation between molecular structures and desired transport phenomena, while paving the ways for future technological advances.

What makes our research most fun is the opportunity to tackle emerging scientific problems at the intersection and forefront of Physics, Chemistry, Engineering and Nanoscience, and to work/collaborate with leading scientists/researchers in these areas. You are always welcome to checkout our research, join us, collaborate with us, and most importantly have fun with us together.
