For the moment I want to calculate the electronic characteristics (DOS, bandstructure, etc.) of the nanoribbon as bulk. Is then 1x1x9 ok for this part?
Afterwards, I will use VNL to create a device in order to compute the transport characteristics (transmission spectrum, transmission pathway, etc). I suppose I should calculate the k-point mesh again at this point. It should be 1x1x80 approximately, right?
