Abstract
We describe in detail the different steps involved in the construction of a carbon nanotube (CNT) field-effect transistor (CNTFET) based on a network of single-walled CNTs (SWCNTs), which can selectively detect toxic gases. Due to the absorption feature of the allotropes of carbon, they can be used to make different devices. Absorbing materials by CNTs can change its electrical properties, which can be used in manufacturing the chemical sensors. One specific type of electrochemical SWCNT sensors is the so-called CNTFETs. The operation principle of these sensors is based on the changes in the I–V curves of nanotubes as a result of adsorption of specific molecules on their surface.
