hello all
i have two question 1- i want to ask you how can i do the best geometry optimization(relaxation) when i have a device before transiesta: left e + cenrtal region + right electrode.please tell me in details ( geometry constraint- cg detail). my device is a planar graphen nanoribbon diode . how can i define electrodes (semi infinte).and if u can please attach one of your big cg run examples2- this device has about 500 atoms ( 400 atoms central-100 atoms electrode) what computing system i should use ? core i7 -8core and 32 GB RAM is enough? my device is 2D (planar) best regards.
