In-plane impedancemetric ammonia sensing of solution-deposited, highly semiconductor-enriched single-wall carbon nanotube submonolayer network gas sensors

- Impedancemetric characterization of NH3 gas sensors based on 99% semiconductor-enriched SWCNT networks.
- Impedancemetric operation mode of approximately twice that of a dc measurement.
- Impedancemetric data clearly revealed the role of the absorbed gas molecules.
