Outline of Final Research Achievements

Optical and optoelectronic properties of individual carbon nanotubes in field effect devices have been investigated. Split-gate diodes have been used to demonstrate cold exciton electroluminescence, while molecular screening effects on exciton-carrier interactions have been studied using field effect transistor structures. Screening effects from molecules have been utilized to demonstrate all-optical memory operation and spectral tuning of optical coupling to microcavities. Organic molecule adsorption has been used to achieve larger screening effects and to generate trions by inducing carriers.

Academic Significance and Societal Importance of the Research Achievements

加熱の影響が無視できる状況でカーボンナノチューブの電界発光が実現できることを初めて示すことができた。また、キャリアと吸着分子による複雑な遮蔽効果を紐解き、物性を制御して応用するための基礎的な知見を得ることができた。これらの成果は、シリコン基板上の電気駆動のナノスケール光源や高密度で集積可能な光メモリなど、ナノスケールのフォトニクスへの応用が期待される。
