Abstract

An investigation of the influence of organic vapor (ethanol, methanol and acetone) on the characteristics of simple-structure sensors fabricated from single-walled carbon nanotube (SWCNT) thin films is reported. SWCNTs were directly deposited, by using atmospheric pressure CVD using alcohol-ferrocene mist, on the patterned Al electrodes to fabricate a sensor. It was found that the characteristic of SWCNT-based sensors depended on the depositing position in CVD reactor. The sensor response could be optimized by adjusting the depositing position along the inner quartz reactor. The sensor reproducibility could be improved by light soaking after switching to air. © 2006 IEEE.
