Thank you for visiting our homepage. We are focusing on pulsed laser deposition of abundant element oxides controlled at a nanometer scale. Our goals are to (i) develop new functionalities for electronics device or catalysis application and (ii) to create novel artificial electronic states. Our recent achievements include the fabrication of atomically flat MgO(111) polar surface (Phys. Rev. B 82, 033408 (2010)) and tuning of the surface work function by depositing MgO(100) thin films (Phys. Rev. B 83, 115435 (2011)), where the nanometer scale control in abundant element oxides plays a key role. Our dream is to induce the most striking functionality out of the materials whose bulk characteristics are the most boring!

 

About myself: I started my scientific carrier by studying the electronic structure of  heavy fermion materials by photoemission spectroscopy. I received a DSc degree in physics at Department of Physics, University of Tokyo in 1999, supervised by Prof. Atsushi Fujimori. The title of my thesis is “High-Resolution Photoemission Study of Kondo Insulators.” (You can download the pdf file of my thesis.)  In 2000 I got a postdoc position at RIKEN, investigating metal adatoms deposited on metal surfaces by photoemission spectroscopy with Prof. Maki Kawai. After spending three years at RIKEN I switched the field to oxide thin film study: Since 2003 I was a research associate at Department of Advanced Materials Science, University of Tokyo, where I studied the junction characteristics and electronic states of oxide heterostructures and oxide-metal Schottky junctions with Prof. Harold Y. Hwang. In 2007 I moved to Tokyo Tech.

When I was undergraduate (also at Department of Physics, University of Tokyo) I studied hard x-ray astrophysics (Prof. Tsuneyoshi Kamae Group) and model calculations of two-dimensional electron system (Prof. Hideo Aoki Group).
