Carbon nanotube field-effect transistor

Carbon- nanotube field effect transistor ( English carbon nanotube field -effect transistor, CNTFET ) is a further development of the field effect transistor ( FET), wherein the parts of the semiconductor structure by the carbon nanotubes (CNT) have been replaced.

The first functional CNTFETs were presented in 1998 by a group of University of Delft.

The CNTFETs are smaller than the present ( 2010) are commonly used in microelectronics metal-insulator- semiconductor field-effect transistors based on silicon and are considered one of the components that could replace them in the coming years or decades. In addition to the size, the higher electrical conductivity of the CNTs and the associated higher achievable switching and transit frequencies is a significant advantage of this technology. Big problems currently preparing even the targeted production of the individual transistors.
