Self-assembled carbon-nanotube-based field-effect transistors

Abstract

Self-assembled carbon-nanotube-based field-effect transistors (CNTFETs) were produced with high yield using the natural process of DNA hybridization. In principle, the devices made by this method behave like those made using direct metal-carbon nanotube contacts. The inverse subthreshold slope of the CNTFETs depends on the source-drain voltage applied to the device, confirming that the conductance of CNTFETs is determined by the Schottky barriers at the interfaces between the CNTs and the gold electrodes.
