Abstract

We experimentally present the multiwalled carbon (MWNT) based gas sensor by a direct nano-wiring between Nb electrodes. Upon exposure MWNT to NH₃, the electrical resistance of the MWNTs is found to increase. The increase of temperature and gas concentration actually reduces the response time and increases the sensitivity to introduction of gas, respectively. Our results show a promising technique for forming CNT bridges between electrodes for chemical gas sensor at room temperature.
