Abrupt bouncing values in scattering rate

AMSET

Dear Alex,

I am now calculating the Bi2Se3.

While checking the energy vs scattering rate graph, I can see values that suddenly jump at a specific energy point.

Here is the question. Is there a rule of thumb to check if this is correct or an error?

I’m not sure where to start and how to check if this is a “calculation error” or “real physics”.

rate2

Hi Euicheol_SHin

Were you able to fix this problem? I also have similar issues with my scattering rate calculation for GeS intercalated with chromocene. There is a bump in the plot of scattering rates (s-1) vs energy (eV) and I wonder if the error is coming from my inputs. I’ll appreciate any advice you can give me.
Thanks.
