| Outline of Final Research Achievements |
We aimed to develop high-performance organic electronics devices by nano-structure control and new condensed matter physics by chemical metal doping and electric double layer.
Subject 1 focused on the control of nano-structure and surface structure of organic semiconductor crystalline film to improve the performance of organic electronics devices. Subject 2 focused on the elucidation of the relationship between the location of intercalated metal atoms and superconducting properties in the metal-doped hydrocarbon superconductors and various two-dimensional (2D) layered materials. Subject 3 focused on the research for the physical properties by field-effect charrier doping to various two-dimensional (2D) layered materials, the search of the novel electron phase using EDL, a transition from a Mott insulator to a superconductor in alkali-doped fulleride superconductors, which was observed for the first time in three-dimensional materials, and the novel electron phase using superlattice.
