Dear Laura, If you have installed siesta with netcdf support, my suggestion is using sisl utility. In this regard, you need to work with ElectrostaticPotential.grid.nc file (created by transiesta), and sgrid command in sisl. for more information see https://doi.org/10.5281/zenodo.597181;

Dear users, I need to know the value of the total electrostatic potential of a molecule, defined as the sum of the hartree potential plus the local pseudopotential. I produced SystemLabel.VH. How can I do it? Best, Laura

The difference between the Hartree electrostatic potential VH(v) - VH(0) is the potential induced by the applied bias. You may refer to this as the potential profile or potential drop in the device region. For instance the potential profile shown in this article www.doi.org/10.1039/c5cp04613k is

Dear all, If we consider for example pure GNR device, we expect that the Hartee electrostatic potential drops linearly through the device length. In the situation that we have some p-dope or n-dope impurity atoms the electrostatic potential evolution is not linearly anymore , however if we

Maybe it is the influence of the semi-infinite leads but I am not sure. Have you done your calculation of electrostatic potential with SIESTA? Also, perhaps, you can subtract this potential from the potential you get at higher voltages. On Sun, Aug 13, 2017 at 11:41 PM, Nick Papior

If your system is a semi-conductor (gapped nano-ribbon) then the fermi level of the electrodes and the device need not coincide. In such cases there is an intrinsic offset in the potential between the two calculations and the band-bending you see is introduced. This is what I *presume* is the
