Our group have two research areas. One is instrument design and development of surface analsis. High lateral resolution imaging using a combination of focused-ion-beam and a time-of-flight mass spectrometer realizes both inorganic and organic species imaging down to 40 nm resolution. The other research is on organic electronics devices. A new fabrication method is devised and studied, named electro-spray deposition (ESD). The aim of this study is energy-saving through the fabrication process.
