Dear all, my question is related to graphene transmission calculation using transiesta (currently I'm using siesta 4.1b4).
I tried to obtain transmission for graphene sheet using geometry given in Figure 3a (https://www.beilstein-journals.org/bjnano/articles/6/164) using the same set parameters. However while i get the correct shape of the curve, my transmission value is n times higher, where n would be be number of zigzag unit cells contained in the given graphene sheet. If I use single zigzag unit cell I am able to reproduce the correct result. My question would be, is there a problem with my siesta installation or is there a parameter that I am missing the would give correct value of transmission. If neither is the case, what is the implication of this when i want to calculate transmission of graphene gap with a molecule (when i need to use larger graphene sheet like the one from Figure 3a). Kind regards, Aleksandar
