Dear Zahra,
The value of the total electrostatic potential of a molecule is defined as
the sum of the hartree potential plus the local pseudopotential.
So..
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

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

Dear Nick,
Thank you for your clarification.

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.

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
