Our research focuses on describing details of the energy transport and conversion at the solid surfaces and interfaces in the nanoscale regime. In order to understand their basic mechanism at a single molecule/atom level, we carry out combined study of density functional theory calculation and scanning probe microscopy/spectroscopy on the well-defined solid surfaces under ultra-high vacuum condition. Part of our research is directed toward investigation of single-molecule chemistry on various solid surfaces. Another important part of our research focuses on self-assembled organic thin films aiming at understanding their microscopic structure and controlling their electronic properties. In addition, we also investigate energy conversion between electrons and photons of the nanometer scale materials.
