Abstract
An organic thin film transistor may comprise an organic semiconductor layer having surface-modified carbon nanotubes and an electrically-conductive polymer. The surfaces of the carbon nanotubes may be modified with curable functional groups, comprising oxirane groups and anhydride groups. A room-temperature solution process may be used to provide a relatively uniform and relatively highly-adhesive organic semiconductor layer in a simple and economical manner. Additionally, the organic thin film transistor having the organic semiconductor layer may have relatively high charge carrier mobility and relatively low threshold voltage.
