Outline of Final Research Achievements

Using angle-resolved photoemission spectroscopy (ARPES), we investigated the correlation between geometric and electronic structures in highly ordered organic thin films and interfaces. We succeeded in observing various new findings related to molecular electronic functionalities such as (1) the delocalized π-d hybrid state in the two-dimensional organic-metal network, (2) the long-range intermolecular interaction in flat-lying molecular monolayers, and (3) the Kondo resonance at the organic/metal interface. Furthermore, we developed a new ARPES spectrometer (acceptance-cone-tunable spectrometer: ACT) to measure the photoelectron intensity angular distribution with high efficiency and resolution.

Academic Significance and Societal Importance of the Research Achievements

有機半導体の分野では、分子間バンド分散を決定すること自体が困難な主題である。申請者は試料作製と分光測定の両面を独自の方法で高度化することで、従来は困難を極めた分子間バンド分散の系統的研究を実現した。これにより、分子系に特有の様々な非本質的現象の中に埋もれていた新奇かつ重要な電子物性に関する知見を得た。本研究成果は、有機半導体の本質の解明と高機能化に貢献すると共に、実験データ不足のため最適な近似レベルが確立されているとは言い難い電子状態計算などの他分野に対する指導原理をも提供でき、多方面の分野への波及効果を期待している。
