- September 2001 - March 2026
- Affiliation
- Division of Condensed Matter Science
Research Subjects
- Development and studies of structural and physical properties for novel organic (super)conductors and proton conductors based upon molecular degree of freedom
- Development and studies of structural and physical properties for electron-proton coupled molecular functional materials
- Studies of responses by external stimuli (magnetic and electric fields, temperature, pressure) for molecular materials
- Study of organic fi eld eff ect transistor
I focus on molecular materials composed of condensed molecules with internal degrees of freedom, exploring their unique functionalities, including electron and proton conductivity, magnetism, dielectric properties, and responses to external stimuli such as pressure and electric fields, as well as field-effect transistor characteristics. The development of these novel functional molecular materials provides fundamental research for materials and devices underpinning organic electronics, including solution-processed organic conductors and electrolytes for fuel cells.
