Performance Analysis of (13,0) and (17,0) Carbon Nanotube Field Effect Transistors (CNFETs)

Abstract

This paper explains the comparative analysis of the performance of (13,0) and (17,0) carbon nanotube field-effect transistors (CNFETs). The comparison is done by studying the output and transfer characteristics of CNFETs. Modeling of the total capacitance of cylindrical CNFETs for the two types of chirality (13,0) and (17,0) has also been reported in the paper. It has been observed that (13,0) carbon nanotube has lesser propagation delay, however, but the drain current is higher for (17,0) for the given parameters. This shows that the switching application is better in case of (13,0) for the given parameters.
