Abstract
This communication describes scanning tunnelling microscopy investigations of
the electronic properties of singlewalled carbon nanotubes (SWNTs). First, the
unique relationship between the atomic structure and electronic properties of
SWNTs is presented. Second, structural defects in nanotubes are addressed, and
quantum size effects in SWNTs are discussed. Lastly, the effects of magnetic
impurities on the low-energy properties of metallic SWNTs are discussed.
Applications and prospects for future research directions are considered.
