Abstract
Gas ionization sensors based on the field ionization from well-aligned MWCNT arrays grown in porous AAO templates were fabricated. The breakdown voltages were measured in different gases of different concentrations. The changes of the breakdown voltage were related to the type of detected gases and its concentration. At the same time, the pre-discharge processes had also been studied to test the responses of the gases sensors to several gases. It was found that the as-prepared gas ionization sensors using well-aligned MWCNT arrays grown in porous AAO templates have shown good sensitivity to acetic acid with short response or recovery time.
