FIG. 1.

Experimental setups: (a) Substrate-supported tube (SST) and (b) freestanding tube (FST). (c) characteristics for long nanotube with different values of coupling coefficient . (d) Temperature in the middle of the tube as a function of the current for different .

FIG. 2.

Features comparison of long -CNT strongly (left) and weakly (right) coupled to the substrate: (a) characteristics, (b) temperature profile as a function of the voltage , and (c) Fermi distribution at midlength for each of the carrier branches at different points indicated in the characteristics. The distance between dashed line corresponds to the optical phonon energy.
