I have some strange problem with your zig-zag nanotube: You write (0,10) nanotube in your image, but everytime I count the hexagons (equivalently to the number of unit vectors along the circumference), it's 14. Did I miss something "theoretically", or is this a real mistake? Thanks for any hint! Jan


It is a not a (0,10), but a (14,0) tube. Zig-zag tubes are generally (n,0), so the first mistake is messing up n and m. The second is as Jan correctly states, that there are 14 a1 vectors around the circumference. BR Jakob

Ooops…

… thank you guys, I messed up. I'll corret that as soon as possible! Mstroeck 09:13, 10 June 2006 (UTC)

Misleading

The picture has several problems:

- (n,n) tubes are called armchair tubes because their circumferential edge is armchair-like (ignoring cut bonds). This is not evident in the (10,10) example since an oblique edge was chosen.

- Likewise, there is a disconnect between the (periodic) bonds shown in half in the (0,10) wireframe and the (0,10) picture -- which still actually is (0,14).

- In a schematic figure like this, color should serve to illustrate a quantity or separate components. Here, it seems just thrown in and the viewer is left to guess. "Depth" in a perspective drawing is better (if at all) illustrated by fogging.

- The black background is unsuitable for printing and most paedagogical uses.

Use of the your image

Dear Michael Ströck,

I would like to ask authorization to use this image "carbon nanotubes" - http://en.wikipedia.orghttps://wikifreehand.com/en/Image:Types_of_Carbon_Nanotubes.png. How do I talk to you about this? My e-mail is [email protected]. Please, write to me. I work in a educational group in Brazil.
