Abstract

A technique of the invention reduces significantly the distance between the gate and single-walled carbon nanotubes to improve performance and efficiency of a carbon nanotube transistor device. Without using a porous template structure, single-walled carbon nanotubes are grown perpendicularly to a substrate between a base metal layer and a middle mesh layer. The nanotubes are insulated with a thin insulator and then gate regions are formed.
