This paper examines aspects of design technology required to explore advanced logic-circuit design using carbon nanotube field-effect transistor (CNTFET) devices. An overview of current types of CNTFETs is given and highlights the salient characteristics of each. Compact modeling issues are addressed and new models are proposed implementing: 1) a physics-based calculation of energy conduction sub-band minima to allow a realistic analysis of the impact of CNT helicity and radius on the dc characteristics; 2) descriptions of ambipolar behavior in Schottky-barrier CNTFETs and ambivalence in double-gate CNTFETs (DG-CNTFETs). Using the available models, the influence of the parameters on the device characteristics were simulated and analyzed. The exploitation of properties specific to CNTFETs to build functions inaccessible to MOSFETs is also described, particularly with respect to the use of DG-CNTFETs in fine-grain reconfigurable logic.
