- Abstract
- Hygroscopic effects on AuCl3-doped single-walled carbon nanotubes (SWCNTs) were investigated. Various concentrations of AuCl3 solution were dropped on the random network SWCNT transistors, where the doping effect was confirmed by I-V-g characteristics and a blue shift in the Raman G band. The AuCl3-doped SWCNT transistor was highly sensitive to water vapor in the I-V-g curve, especially in the positive gate bias region, compared with the undoped SWCNT transistors. We also found the selective response of water from ambient gases, such as O-2 and N-2, in AuCl3-doped SWCNTs. This investigation could be beneficial for high-performance water sensor applications.
