| At a glance | CNTbands v2.0 can simulate electronic band structure and density-of-states for carbon nanotubes (CNTs) and carbon nanoribbons (CNRs). It also computes some basic parameters, such as nanotube diameter, number of hexagons in the unit cell, band gap, etc. Users may select the CNR structure to be simulated by selecting a starting point and components for a chiral vector.

CNTs are simulated either with a simple Pz orbital model or Extended Huckel theory. The Extended Huckel model can deliver more accurate simulation results, especially for small-diameter CNTs. |

the CNTBands tool is very usefull, specialy to appreciate the geometrics and electronics properties. I think that it's a very important tool to use in both cases ( education and research).
It's gives an excellent introduction to the carbon Nanotubes with a explicit 3D graphics, without forgotten the possibility to compare the properties of many CNTs in the same time. however,
there are some problems like the incapacity to simulate some CNTs such as (26,18) chirality.
but mainly I think that the CNTBands is very powerful tool. -

Provides an excellent introduction to the visualization of a 3D carbon nanotube as a function of chirality. Different geometries can be overlaid and compared.
Simple calculations such as dispersions and density of states can be performed. Insigt into the semiconducting versus metallic carbon nanotubes can be gained.
