Research Topics

Surfaces and interfaces are the bridges between the nano-world and the real world. Our group is interested in understanding the physics and chemistry at surfaces. To contribute this understanding, we develop AFM-based nano-tools to characterize various physical and chemical properties and interactions at surfaces on the nanoscale.
