| Outline of Final Research Achievements |
The properties of the Li@C60, which is consisted of lithium cation and anionic fullerene C60-, as dopant was investigated. We fabricated thin film of C60 containing Li@C60. In the film, by the electron doping from Li@C60 to C60 solid state, the controlling of Fermi level and career density was achieved. This result is first example of doping without disturbing the solid-state structure of organic semiconductor.

| Academic Significance and Societal Importance of the Research Achievements |
無機半導体では，その性質を微調整するために，別の原子を少量加える『ドーピング』と呼ばれる処理が一般的におこなれます．有機半導体でも同様の処理がおこなれますが，別の分子を取り込むために，固体構造がドーピング前後で全く異なってしまうという問題がありました．今回，フラーレンの籠状骨格内にリチウム原子を持つリチウム内包フラーレンを用いることで，固体構造を変化させずドーピングを行えることを示しました．
