Abstract

Aqueous solutions of carboxyl functionalized single-wall carbon nanotube (SWCNT) films are deposited on silicon chips by the inkjet printing technique. By varying the film thickness it is possible to obtain low- or high density networks of SWCNTs, having either nonlinear or linear current-voltage characteristics, respectively. The electrical transport in the low-density films is gate-controllable and utilized as chemical field-effect transistor sensors; whereas the high-density SWCNT networks of nearly Ohmic behaviour are used as conventional resistive gas sensors. The response of both types of sensors is studied for hydrogen sulfide (H2S) analyte.
