摘要

有機薄膜電晶體(Organic Thin Film Transistor ,OTFT)擁有製程簡易、製程低溫、結構簡單等等的優勢。若是製作於軟性基板上，其可彎曲的特性更是可以用來驅動各式各樣的軟性顯示器。

本研究藉由化學氧化聚合法的方式,在鹽酸(HCl)水溶液中，以過硫酸銨((NH4)2S2O8，APS)為氧化劑，苯胺(aniline)為單體，聚合成具有導電特性的聚苯胺，並經由氨水(NH4OH)作去摻雜的處理，使此種特性的高分子材料擁有當做有機半導體材料的潛力。

過程中我們再藉由還原金屬奈米顆粒於去摻雜的聚苯胺上去改變材料的導電特性,表面形貌及載子種類，我們嘗試摻雜的金屬包含:金(Au)、鉑(Pt)、鈀(Pd)、銠(Rh)、釕(Ru)以及銀(Ag)，並藉由四點探針(Four-point probe)、場發射電子顯微鏡(Field Emission Scanning Electron Microscope ,FESEM)、紫外光-紅外光-近紅外光光譜儀(UV-VIS-NIR Spectrometer)、傅立葉轉換紅外光光譜儀(Fourier Transform Infrared Spectrometer ,FTIR)等儀器去做分析。

最後我們嘗試將多種不同金屬摻雜的聚苯胺當作有機半導體材料，去製做有機薄膜電晶體(Organic Thin Film Transistor ,OTFT)，並搭配著兩種電極:鈦(Ti)跟金(Au)，去做一系列的量測與探討。
