Controlling Polarity and Threshold Voltage of Carbon Nanotubes Field-Effect Transistors by Efficient Doping Process |
| 초록 |
As introducing the wrapping single-walled carbon nanotubes (SWNTs) via conjugated polymers, the sorting of semiconducting SWNTs can be achieved efficiently for using in solution processing printed electronics. Although the field-effect transistors (FETs) based on sorted SWNTs have shown excellent performance, still a number of challenges are remained such as controlling threshold voltage or achieving highly stable devices. As one of strategies, solution processed doping using dopant is considered as efficient method for continuous processing of printed electronics. This method can be effectively applied to SWNT based FETs. In this study, the high performance top-gated and bottom contact SWNT-FETs, wrapped by conjugated polymer, have been researched with introducing solution processed doping. As applying doping SWNT approach by solution processing into fabrication TG/BC SWNT-FETs, significant effect was observed such as converting polarity, and shift of threshold or turn-on voltages. |
