Scattering approximations in transport calculations

[hongocnam]

Hi everyone,

Related to transport calculations, could you please share related information on the formula or references on the definition of e-ph scattering approximations (ELPH_SCATTERING_APPROX) implemented in VASP? I can find several approximations that are presented as options, but there is not a clear, specific definition of these approaches. Could you please describe the significant difference implemented in VASP or at least the references?
Thank you for your support.

Hi,

Again, sorry for my delay in answering to you.
As I have written in your other post, I have updated the https://www.vasp.at/wiki/index.php/ELPH ... ING_APPROX wiki page to show the different scattering approximations we implemented to solve the Boltzman equation.
