title: Single-walled carbon nanotube thin film gas sensors controlled by diffusion.
abstract: The electrical and gas sensing properties of mat-type thin films fabricated by the packing of single-walled carbon nanotubes are investigated. The responses of the sensors with various thicknesses or resistances are measured, and the behavior is explained by a diffusion model. The successful explanation of the sensor response using the diffusion model suggests that the mat-type structure of compacted carbon nanotubes can be treated as a porous medium for gas sensor applications.
