Our main interest lies in the studies of physical and chemical phenomena that take place in nanometer-scale regions as well as the applications of such phenomena in photo-electronic devices. We investigate materials properties of nano-structures through their optical response to local excitations that is generated by electrons from the tip of a scanning tunneling microscope (STM). The physical systems under study include adsorbed atoms and molecules on solid surfaces, metal and semiconductor nano-structures, and superconductive nano-structures.

We are also interested in developing novel probing methods for nano science. We are developing a STM light emission spectroscopy system that is capable of measuring the optical properties of nanometer scale objects with pico-second time resolution.

Research topics:

  1. Identification of individual surface adsorbates
  2. Single molecule optical spectroscopy
  3. STM light emission spectroscopy of normal and super conductive nano-structures
  4. Light enhancement effect in nano-scale regions
  5. Creation of novel nano-structures by STM
