ELPH_TRANSPORT_EMAX_PLOT = [real]
Default: ELPH_TRANSPORT_EMAX_PLOT = [math]\displaystyle{ \max(\varepsilon_{n\mathbf{k}}) }[/math]+5
Description: Specifies the maximum energy (in eV) to be considered when computing the transport distribution function for plotting.
| Mind: Available as of VASP 6.5.0 |
By default, the upper energy limit is set to [math]\displaystyle{ \max(\varepsilon_{n\mathbf{k}}) }[/math] + 5 eV, where [math]\displaystyle{ \varepsilon_{n\mathbf{k}} }[/math] are the electronic eigenvalues computed in the k-point mesh defined by the KPOINTS_ELPH file. The transport function for plotting is computed additionally to the one that is used to evaluate the Onsager coefficients but allows choosing a different energy range thus not compromising the accuracy of the transport calcualtions.
The transport function and corresponding energy grids are written to vaspout.h5
