About mode-resolved mobility.
Posted: Mon Sep 09, 2019 12:30 pm
Dear EPW developers,
Recently we are using EPW to calculate the transport of two-dimensional materials like antimonene monolayer. Since EPW does not output the mode-resovled information about the coupling between electron and respective phonon modes, so, in order to calculate the phonon mode-resolved mobility in the Self Energy Relaxtion Time Approximation, we modify the code of transport.f90 as follows. In this way, the respective six phonon modes in our case can be investigated.
1. Added INTEGER::NMODE after the original 136 lines.
2. Added NMODE = nmodes(nomdes = 1, 2, 3, 4, 5, 6 respectively).
3. Added nmodes = NMODE after the original 536 lines.
After modification, we run the respective codes and calculate mode-resolved and total mobility, but we found that the calculated curves are not correct. We have examined the code several times, but we can not locate the problem. Could you please give me some suggestion on how to modify the code to calculate mode-resolved mobility?
Thank you very much!
