Default: ELPH_TRANSPORT = .FALSE.
Description: Activates transport calculation involving electron-phonon coupling
| Mind: Available as of VASP 6.5.0 |
When ELPH_TRANSPORT = True, VASP calculates the transport coefficients from the linearized Boltzmann transport equation.
In this framework, the transport coefficients are calculated from various relaxation-time approximations selectable via ELPH_SCATTERING_APPROX.
A convenient way to start transport calculations is to set ELPH_MODE = transport, which automatically provides reasonable default values for the required INCAR tags.
