IFC_LR = [integer]
Default: IFC_LR = 1 

Description: Controls the treatment of the long-range part of the interatomic force constants during electron-phonon calculations.


This tag controls the treatment of the long-range electrostatic contributions to the interatomic force constants (IFC) arising in polar dielectric materials. IFC_LR = 1 has the same effect as LPHON_POLAR = True but is used in the context of electron-phonon interactions.

Modes

IFC_LR ≤ 0
No long-range correction scheme is applied to the IFC matrix. This is most likely very inaccurate for semiconductors and insulators with non-vanishing Born effective charge.
IFC_LR = 1
Dipole corrections are applied to the IFC matrix.
