Electronic transport measurements on boron/nitrogen co-doped single-walled carbon nanotubes (BCN-SWNTs) have been performed to determine their metallic or semiconducting character. The results obtained from a large number of BCN-SWNT-based field-effect transistors indicate that the as-grown BCN-SWNTs are purely semiconducting, while the undoped C-SWNTs consist of only about 70% semiconducting nanotubes.
