Question about Electrostatic Potential and Electrostatic Difference Potential

[kaypu]

Dear QuantumWise staff
             
      What does the Electrostatic Potential consist of when the bias is applied? Does it equal to the Hartree energy?  or equal to the sum of Hartree energy and the electro-static external potential (bias potential)?

[zh]

In the pseudopotential method, the electrostatic potential consists of Hartree potential and the local part of pseudopotential.  It does not include the bias potential.  The bias potential corresponds to the change of electrostatic potential after and before the application of bias.
