[QE-users] SCF potential in Born effective Charge

[Shubham Patel]

Dear developers and Experts,

Is it possible to collect/extract the dV^KS/du term as shown in the picture attached using QE-PHonon? This is a formula for calculating the Born effective charge. I am sure this data is stored somewhere (most probably in the binary files *.dvscf). If someone knows how can I collect this data, and if there is any utility in QE please let me know. I would really appreciate the help.

Thank you very much.

Sincerely,
Shubham Patel
