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 tbtrans for every bias or just running transiesta for 0 bias and then tbtrans for all the bias values. I think that this question is answerd easyly: yes or no. Let me know if I had to deliver details of the calculation I expect to do.
