... extrinsic doping of the tubes (adsorbed oxygen, for example, may strip electrons from the tube and dope it to p- type). The thermal transport of nanotubes is of special interest, in part because nanotubes ... excitation spectrum. In particular, sharp transitions are expected for optical absorption. Early optical studies of nanotubes were hampered by clustering of the tubes in...
