| Outline of Final Research Achievements |
Properties of several materials were controlled employing electrical-double-layer transistor, which utilizes strong electric field at interfaces between solid and electrolyte. In particular, a field-effect resistivity change in a resistance of metallic single-walled carbon nanotubes was realized. In situ optical absorption spectroscopic measurements revealed the resistance change is due to a change in a subband number. For organic semiconductors, reductions of electron injection barriers and changes in distributions of trapping levels were realized by controlling metal-semiconductor and insulator-semiconductor interfaces, respectively.
