Solution Deposition Methods for Carbon Nanotube Field-Effect Transistors

Extensive research has been done on carbon nanotube field-effect transistors (CNTFETs), which may revolutionize electronics. Single-walled carbon nano-tubes (SWNTs) act as the channel between the source and the drain of the transistor device. CNTFETs can have very high on/off current ratios, but the presence of metallic CNTs, in addition to semiconducting CNTs, reduces the on/off ratio significantly. Therefore, the CNT thin film has a major influence on the transistor behavior and must be carefully developed.
