Optical second harmonic spectroscopy of surface and interface phenomena
We develop optical second harmonic spectroscopy and use it as a tool to monitor the change of surface and interface electronic levels during important surface and interface phenomena. The electronic structure as well as the orientation and the order of the surface bonds and adsorbates, of photo-catalysts, surface/ adsorbate systems, semiconductor interfaces and superconductor surfaces are our main interest.
Vibrational spectroscopy of surface adsorbates by observing Raman scattering and sum frequency generation
We investigate the mechanism of surface and interface phenomena such as surface oxidation or catalytic reaction, by analyzing the vibration of molecules involved. For this purpose we have developed a high-sensitive Raman spectrometer and sum frequency spectroscopy system. We are interested in clarifying the adsorption state of molecules on catalysts and the order of water clusters in the vicinity of bio-materials.
Materials to be realized only on surfaces
The properties of atoms, molecules, and films on surfaces are dramatically different from those in the free state. Investigating the origin of this difference, we take advantage of it to realize materials with properties possible only on surfaces.
Development of an optical second harmonic microscope and an optical sum frequency microscope
We develop an optical second harmonic microscope and an optical sum frequency microscope in order to observe the spatial distribution of electronic states of interesting surfaces. The microscopes are planned to have good spatial resolution and to be capable of tuning the excitation wavelength in a wide region. We are planning draw new physics from the nonlinear optical images of catalysts, semiconductors and living organisms.
