本研究主要探討五環素與四環素製備之有機薄膜電晶體在彎曲實驗之下的載子傳輸特性。首先利用彎曲後蒸鍍之方式製作具有壓縮應力(內彎曲)的半導體薄膜，製作成彎曲有機薄膜電晶體，與未彎曲的有機薄膜電晶體進行相互比較與討論。電晶體在內彎曲後之載子移動率會有明顯提升，與文獻所研究結果相符合。五環素電晶體在內彎曲後之載子移動率上提升了25.8%，而在四環素電晶體提升為2.1%。在驗證部分，利用X光繞射儀與紫外光/可見光光譜儀來進行分析後，發現有機薄膜電晶體在內彎曲下之載子傳輸，不僅受到文獻上所強調之分子耦合作用力提升影響，亦須考量重組能在彎曲之後所造成之影響；而此兩項因子的提升，所造成之載子跳躍率變化，也更加符合實驗中電晶體載子移動率的變化，達到更準確了解有機薄膜電晶體在內彎曲下與電性變化效果之關係。本實驗提出一個簡單的驗證模式，來探討有機薄膜電晶體內彎曲後載子移動率變化，也因此提供了一個簡易的方法，來選擇有機半導體材料應用於軟性電子領域等上。

Pentacene- and tetracene-based thin film transistors under bending conditions are demonstrated. Transistors with compressive strain showed improvement in field effect mobility which was greater in pentacene transistors but only slight enhancement in tetracene transistors. The intermolecular coupling (transfer integral) effect is verified through theoretical calculation of Davydov Splitting from X-ray diffraction (XRD) and experimental results of ultraviolet/visible light (UV/VIS) spectra measurement. More information about reorganization energy is provided in UV/VIS spectra which also play a critical role in dominating the carrier transport. The data of XRD and UV/VIS spectra provide appropriate measurements for choosing organic electronic materials in bending applications.
