Dear Siesta users
I have used Transiesta to study a graphene based transistor. I want to calculate the gate-bias modulation effect on this structure. When I set the external electric field perpendicular to the Z-direction along with source-drain bias (TS.Voltage), I always get such warning: WARNING: both ext. voltage and field !! WARNING: will neglect voltage !! It will be very kind of you if can help me. Best regards, Nayereh Ghobadi
