Mobility Results Mismatch

[Agathyan]

Dear All,
I calculated Si mobility via EPW Summer School 2018 tutorial (Resistivity and Mobility) using a 100x100x100 k/q-mesh. Though the profile match, the amplitudes don’t match the tutorial. Kindly help me match the result (from paper: https://arxiv.org/abs/1803.05462)

Hello,

To match results in https://arxiv.org/abs/1803.05462, you need to converge your calculations with respect to both coarse k-q grids (nk, nq in epw calculations) and fine k-q grids.

To converge calculations for Si, you can use the input files provided with the manuscript here:https://journals.aps.org/prresearch/abs ... h.3.043022. You can find the inout files in materials cloud archive here:https://archive.materialscloud.org/records/n1bqf-t7441.

Best regards,
Sabya.
