Build a graphene nanoribbon again

[keditu]

Dear experts,

I'm a new member in a laboratory of nanoeletronics and my 1st task is to calculate band structure, DOS and IV curves in graphene nanoribbons. But our lab still has an oldest version of virtual nanolab (2008.10).

I want to build graphene nanoribbons and i'm not be able to do that. I was looking for the solution in the forum, and i found a script (graphene_ribbon.py) that do that. Unfortunately that script is not on line anymore.

Could anyone tell me how  can i build a graphene nanoribbon in that version? Or could anyone send me that script?

Thanks in advance,
Keditu.

helo friend...
i am also having the same problem...but i suggest you to download the new atk version 11.2.1...in that it is very easy to generate it and also easily you can calculate the band spectrum and other things...although these calculation are also possible in 10.8 but the task is difficult for a new user until some is their to help you...
