Outline of Final Research Achievements

We elucidated molecular origins that lead to structural disordering at organic heterointerfaces, employing scanning tunneling microscoopy (STM) and ultraviolet photoelectron spectroscopy (UPS). Direct observation of disordered F16CuPc/6T interface with STM clarified what is the structural disordering upon the interface formation. Moreover, we could reveal the impacts on structural disordering by molecular size, molecular conformational flexibility, and heteromolecular interaction.

Academic Significance and Societal Importance of the Research Achievements

有機半導体界面の表面科学的な評価を通し、「構造が無秩序化した」という表現はこれまでにも数々の論文で見受けられる。しかしながら、具体的に、構造が不均一化した箇所では分子がどのような状態にあるのか、をSTMを用いて明確にできたことに、学術的な意義があると言える。加えて、分子間相互作用の大きさや、剛直さの異なる分子を組み合わせることで、界面構造を制御できることも発見し、機能発現の要となる有機ヘテロ界面の設計、ひいてはデバイス設計につながる知見が得られた。
