General Questions and Answers / Re: how to define nanoribbon width

« on: October 11, 2014, 09:22 »

well if you have vnl 13.0 then simply go to builder and click on add near to stash and Add-> from plugin-> Nanoribbon. click on one of the optins say armchair edge.that will give you GNR with armchair endings.Then you provide the value in given box in terms of 'atoms wide' .and that is your no or dimers that belong to classes .lik for example if you want to form a 3p+1 class GNR then give for e.g. p=3 then 3p+1 will be equal to your 'atoms wide ' optins.put ten inside the box and build it.then go to bulk tools to repeat the structure in order to give the length of the wire.
