Carbon nanotubes (CNTs) have high mobility and mechanical flexibility, making them promising for flexible electronics applications. In CNT thin-film transistors (TFTs), degradation of electrical properties due to surface adsorbates such as surfactants and resist residues has been reported, so removal of these surface adsorbates is important. In this study, we attempted to remove adsorbates by vacuum heating treatment and evaluated its effect on the electrical and interfacial properties of CNT TFTs.
