A facile method for the fabrication of negatively and positively charged rGO field effect transistors (FETs) is proposed, which utilizes electrostatic attraction between electrodes and rGO sheets. Negatively and positively charged rGO sheets are functionalized with carboxylic acid and amine groups, respectively. The FET of amine-functionalized rGO exhibits an n-doping effect. The FET devices fabricated by this method show high mobility of carriers.
提出了一种简便的制备带正负电荷还原氧化石墨烯场效应晶体管（FET）的方法，该方法利用了电极与还原氧化石墨烯片之间的静电吸引作用。带负电荷和正电荷的还原氧化石墨烯片分别用羧酸和胺基团功能化。胺功能化还原氧化石墨烯的 FET 表现出 n 掺杂效应。通过这种方法制备的 FET 器件表现出高载流子迁移率。
