Abstract :
This paper gives an overview of some potential uses of carbon nanotube field effect transistors (CNTFETs) in logic circuit design. The realization of existing logic functions with resistive-load and complementary logic is described, with some examples of how a logic function can be coded by selective doping of a single nanotube molecule. The exploitation of properties specific to CNTFETs to build functions inaccessible to MOSFETs is also evoked, particularly with respect to geometry-dependent threshold voltages in multiple-valued logic, and to the use of ambivalent CNTFET characteristics in reconfigurable logic
