Abstract :
We report on the fabrication and measurements of the first NO2 gas sensors based on individual suspended single-walled carbon nanotubes (SWNTs). We analyze the transient current response of two types of SWNTs when exposed to NO2 in dry and humid air. Furthermore, we analyze the change in the gate characteristic of the SWNTs due to NO2 and propose two different transduction mechanisms in suspended SWNTs.
