Gas sensing performance of as-produced CNWs. (a) SEM image of CNWs bridging two neighboring Au fingers of an interdigitated electrode.
Gases are detected by measuring the change in the device current while applying a
constant dc bias to the device. (b) Room-temperature sensing response for NO2 and NH3.
