**Questions and Answers / scf convergence for finite bias device calculation**

« **on:**February 4, 2021, 10:30 »

my zero bias calculation for both parallel and anti-parallel configuration, as well as finite bias 0.05v calculation for parallel configuration, converges well, but when I do 0.05V calculation for anti-parallel geometry, the calculation doesn't converge at all. I have used the zero bias calculation as the initial state for the finite bias 0.05V calculation and damping factor 0.05, history steps 12. I have attached my script file for your reference.
