Zigzag and spiral configurations for fullerenes in …

2007-6-19 · Two nonlinear patterns for a C 60 fullerene chain inside a single-walled carbon nanotube, which are assumed to be zigzag and spiral, are examined in this paper. We employ the Lennard–Jones potential function and the continuum approximation to obtain the energy of the system which upon minimizing gives rise to the stable structure of the system.

Electrical conductivity of zigzag carbon nanotubes ...

Electrical conductivity of metallic zigzag carbon nanotube is investigated in the context of Holstein model using Green's function approach. The effects of radius of carbon nanotube, temperature and electron phonon coupling strength on the electrical conductivity of zigzag nanotubes are investigated. It is seen that electrical conductivity increases as a function of temperature at low ...

The Electronic Properties of the Graphene and Carbon ...

3.1. Zigzag Carbon Nanotubes. In Figure 1(b) we show the band structure of an isolated (6, 0) nanotube. Also, Figure 1(a) contains the graphene electronic dispersion. The right part of both graphics is the density of state of graphene and nanotube. The supercell graphene and isolated (6, 0) nanotube include 24 carbon atoms.

what is a zigzag nanotube? | Yahoo Answers

2006-11-12 · A zigzag nanotube is a carbon nanotube with a particular orientation. If you imagine that the structure of the carbon atoms make up lots of little pentagons and hexagons. If you put the hexagons side by side so that straight edges were touching and look along the top then you can see that they have jagged or zig-zag edges.

2015-5-11 · How a zigzag carbon nanotube grows. ... Through first-principle calculations, we found that, because of the high energy barrier of initiating a new carbon ring at the rim of a ZZ CNT, the growth rate of a ZZ CNT is proportional to its diameter and significantly (10-1000 times) slower than that of …
