Gate-all-around carbon nanotube transistor with doped spacers

摘要

A method of fabricating a semiconducting device is disclosed. A carbon nanotube is formed on a substrate. A portion of the substrate is removed to form a recess below a section of the carbon nanotube. A doped material is applied in the recess to fabricate the semiconducting device. The recess may be between one or more contacts formed on the substrate separated by a gap.
