Indium-tin-oxide single-nanowire gas sensor fabricated via laser writing and subsequent etching

- A novel method to generate ITO nanostructures by laser annealing and subsequent etching.
- A novel application of ITO nanowires as self-heated gas sensors at temperatures below 200 °C.
- A basic characterization of this ITO nanowire-based gas sensor was performed.
- Presentation of two possible theoretical approaches to explain the results.
