Carbon nanotubes (CNTs) are promising materials for gas sensors because of their large specific area and high sensitivity to charge differentiation. In this study, we fabricated ambipolar CNT-FETs by the dielectrophoretic assembly to investigate and compare these effects on NO₂ gas exposure through electrical properties.
