CNTFET-based logic circuit design

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
