What is the reason why carbon nanotubes conduct electricity?

Carbon nanotube have recently emerged as an important nanomaterial with enhanced properties such as high electrical & thermal conductivity, aspect ratio, and toughness. To get electrons to flow through a semiconducting carbon nanotube.Carbon nanotubes conduct electricity better than metals. When electrons travel through metal there is some resistance to their movement. This resistance happens when electrons bump into metal atoms.They are considered the ideal candidate for electronic devices, biosensor hydrogen storage cells, electrostatic discharge, and electrical shielding applications.
