A solution-processable technique combining drop-casting and shadow-mask deposition was developed for the fabrication of field-effect transistors based on carbon nanotube random networks. The proposed technique, which is easy, fast, and reliable, allows direct control of network density and thus of the transistor characteristics. A systematic study has been carried out on the factors influencing the transistor performance, which provides novel knowledge and guidance for future device optimization.     «
