本発明の有機半導体膜、有機半導体デバイス、有機薄膜トランジスタについて説明する。
《有機薄膜トランジスタ1の作製》
ゲート電極としての比抵抗0.01Ω・cmのSiウェハーに、厚さ200nmの熱酸化膜を形成してゲート絶縁層とした後、オクタデシルトリクロロシランによる表面処理を行った。
比較化合物2(2,3,9,10−テトラヘキシルペンタセン)は、Organic Letters、vol.2(2000),p85に記載の方法で合成した。
有機薄膜トランジスタ1の作製において、比較化合物1を比較化合物3(ルブレン、アルドリッチ社製、市販試薬を昇華精製して用いた)に変更した以外は同様にして、有機薄膜トランジスタ3を作製した。
有機薄膜トランジスタ1の作製において、比較化合物1の代わりに、表1に記載の本発明の有機半導体材料に変更した以外は同様にして、有機薄膜トランジスタ4〜8を作製した。
得られた有機薄膜トランジスタ1〜8について、各素子のキャリア移動度とON/OFF比を、素子作成直後に測定した。なお、本発明では、I−V特性の飽和領域からキャリア移動度を求め、さらに、ドレインバイアス−50Vとし、ゲートバイアス−50V及び0Vにしたときのドレイン電流値の比率からON/OFF比を求めた。
《有機薄膜トランジスタ9〜13の作製》
実施例1と同様に、ゲート電極としての比抵抗0.01Ω・cmのSiウェハーに、厚さ200nmの熱酸化膜を形成してゲート絶縁層とした後、オクタデシルトリクロロシランによる表面処理を行った。
実施例1と同様に、得られた有機薄膜トランジスタ9〜13について各素子のキャリア移動度とON/OFF比を、素子作成直後に測定した。なお、本発明では、I−V特性の飽和領域からキャリア移動度を求め、さらに、ドレインバイアス−50Vとし、ゲートバイアス−50V及び0Vにしたときのドレイン電流値の比率からON/OFF比を求めた。
塗布プロセスによって形成できることが確認された。
《有機EL素子の作製》
有機EL素子の作製は、Nature,395巻,151〜154頁に記載の方法を参考にして、図3に示したような封止構造を有するトップエミッション型の有機EL素子を作製した。なお、図3において、101は基板、102aは陽極、102bは有機EL層(具体的には、電子輸送層、発光層、正孔輸送層等が含まれる)、102cは陰極を示し、陽極102a、有機EL層102b、陰極102cにより、有機EL素子102が形成されている。103は封止膜を示す。なお、本発明の有機EL素子は、ボトムエミッション型でもトップエミッション型のどちらでもよい。
