Comment on 'Electrical transport via variable range hopping in an individual multi-wall carbon nanotube'

The temperature dependence of the conductance of an individual multi-wall carbon nanotube (MWNT) measured over a temperature range of (297-4.8 K) by Khan et al (2008 J. Phys.: Condens. Matter. 20 475207) is interpreted in the framework of the phonon-assisted tunnelling model. It is shown that our pr...

Description
Summary:The temperature dependence of the conductance of an individual multi-wall carbon nanotube (MWNT) measured over a temperature range of (297-4.8 K) by Khan et al (2008 J. Phys.: Condens. Matter. 20 475207) is interpreted in the framework of the phonon-assisted tunnelling model. It is shown that our presented model describes more adequately the peculiarities of the temperature dependence of the conductance in individual MWNTs supposing that in the process of tunnelling phonons of 1 and 2 meV energy are invoked.
