Abstract: A low-resistivity carbon nanotube aggregate includes a plurality of carbon nanotubes each having one or more walls, wherein a ratio of a total number of carbon nanotubes that have two or three walls relative to a total number of said plurality of carbon nanotubes is 75% or greater, and wherein, in a G band of a Raman spectrum in the Raman spectroscopy of the plurality of carbon nanotubes, a G+/Gtotal ratio that is indicative of an amount of semiconductor carbon nanotubes relative to metallic carbon nanotubes is 0.70 or greater.
