[Pw_forum] Unit of electron phonon matrix elements in ph.x

[WangRiping]

 Dear pwscf users,


I want to know the unit of one quantity calculated by ph.x.
It is electron-phonon matrix elements saved in $prefix.dvscf_q$qnum files.
It is related to the derivation of energy with respect to atomic displacements.  


Best regards.
