Room-temperature printing of CNTs-based flexible TFTs with high performance

Abstract

The flexible field effect transistors (TFTs) play an important role in the application of sensors, artificial intelligence and human-machine interactions and so on. However, the high driving voltage of the TFTs have limited their application in the practical application which require low costs and high performance. Therefore, in our work, the functional semiconducting single-wall carbon nanotubes (f-ss-CNTs) are employed as the semiconducting layer to fabricate the CNTs-based TFTs by room-temperature printing process. The results show that the low driving voltage around 10 V and high on/off ration of 106. Therefore, the CNTs-based TFTs are promising to be applied in a much wider field, such as biosensors and other devices which need low driving voltages.
