Dear Gabriele,
It's very likely as you said. I took a (12,0) 5 layers long for the
system and a 1 layer long for leads; I expected not have neglegible
effect for a bias of 0.4 V and be able to cunclude if running
transiesta is necessary or not. I should admit that I thought this
comparison would be
Dear Juan Manuel,
Guanping explanation is right. I would say in general, it should be the
same whether the local charges in the system don't change significantly
under bias.
This is more likely to happen in a system like a CNT than, for example,
in a single molecule device, where you should start

Dear Siesta Users,
I have a very simple question for those regular users of transiesta
and tbtrans: for plotting IV characteris
Dear Siesta Users,
I have a very simple question for those regular users of transiesta
and tbtrans: for plotting IV characteristics; do I have to run
transiesta for every bias?
I've done a test with a small system (a single wall CNT) and I found
no difference between running transiesta and then tbt
