Hello, users and developers,
I'm now using EPW code. And I face some strange questions.
(1) First, I do a qe calculation to obtain the electron band;
(2) Second, I only choose Wannier code to interpolate my band structures. It works very well;
(3) Third, I decide to run Epw code, however the band looks very poor.

I do not know what happens. Can you give me some suggestions?

Thank you very much

Best wishes

Hi,

EPW basically calls Wannier90 for Wannierization. Therefore, it is highly unlikely that a similar calculation using the two codes for bandstrucutre interpolation would result in a different result.

Did you use same number of Wannierization steps and interpolation grids for both the EPW and Wannier90 calculations?

Best,
Sabya.

Hi Wenjiang,

On top of Sabya's question, could you send us your inputs/outputs and plots?

Happy EPWing,
Hari
