Investigation and Performance of CNT-MOSFET Device Using Quantum-Based Modelling
Abstract: We propose a novel MOSFET design that embodies single wall zig-zag semiconducting carbon nanotubes (CNT) in the channel, as shown in Figure 1. Investigations show that CNTs have high low-field mobilities, which can be as great as 2×105 cm2/Vs. Thus, we predict that MOSFET performance can be improved by embedding CNTs in the channel. To investigate performance of the new CNT-MOSFET device, we develop a methodology that connects CNT modeling …
