Selectively Sorted Single-walled Carbon Nanotubes Using Conjugated Polymers Doping for Carbon Nanotube Field Effect Transistors (CNTFETs) Ambipolarity |
초록 |
Solution-processed active semiconductor doping would be a powerful strategy in order to improve CNTFETs performance in balanced charge transport. CNTs are promising material for high performance, large area printable thin film transistor. However, produced SWNTs (Single-walled carbon nanotubes) shows non-uniform electrical properties. Selective sorting of semiconducting SWNTs using polymer increase considerably with the aim of utilizing their superior properties. We sorted s-SWNTs with the high purity from as-grown mixed-type SWNTs using conjugated polymer with long alkyl side-chain length. Selectively sorted s-SWNTs with dopant is adapted for active layer. The OFET active layer properties and doping effects revealed by UV-VIS spectroscopy, UPS (Ultraviolet Photoelectron Spectroscopy) and low-temperature measurements. We have successfully demonstrated CNTFETs with s-SWNT/n-type dopant bilayer for hole and electron charge balanced transistor by spin coating method. |
