LSU Doctoral Dissertations
The purpose of this study was to develop a complete current transport model for carbon nanotube field effect transistors (CNT-FETs) applicable in the analysis and design of integrated circuits. The model was derived by investigating the electronic structure of carbon nanotubes and using basic laws of electrostatics describing a field effect transistor. We first derived analytical expressions for the carrier concentration in carbon nanotubes for different chiral vectors (n,m) by studying and characterizing their electronic structure. Results showed a strong relation to the diameter and wrapping angle of carbon nanotubes. The charge distribution in a CNT-FET is characterized from the …
