Hello, I have the results for scattering rates, from epw software, but am wondering how I can plot the graphs of scattering rates as a function of energy as we have in this paper fig 1. https://www.nature.com/articles/s41467-021-22440-5 Kindly share some information I will be very grateful. I am using gnuplot ==================================================================== # Inverse scattering time (ps) # ik ibnd E(ibnd) scattering rate(1/ps) 1 3 -0.29205368674922E+01 0.1404112602437623E+002 1 4 -0.29204177603800E+01 0.7328995342445310E+002 1 5 0.33364740729340E+01 0.1817640794169847E+003 2 3 -0.29205368674922E+01 0.1404112602437623E+002 2 4 -0.29204177603800E+01 0.7328995342445310E+002 2 5 0.33364740729340E+01 0.1817640794169847E+003 3 3 -0.29205368674922E+01 0.1404112602437623E+002 3 4 -0.29204177603800E+01 0.7328995342445310E+002 3 5 0.33364740729340E+01 0.1817640794169847E+003 4 3 -0.29205368674922E+01 0.1404112602437623E+002 4 4 -0.29204177603800E+01 0.7328995342445310E+002 4 5 0.33364740729340E+01 0.1817640794169847E+003 5 3 -0.29205368674922E+01 0.1404112602437623E+002 5 4 -0.29204177603800E+01 0.7328995342445310E+002 5 5 0.33364740729340E+01 0.1817640794169847E+003 6 3 -0.29205368674922E+01 0.1404112602437623E+002 6 4 -0.29204177603800E+01 0.7328995342445310E+002 6 5 0.33364740729340E+01 0.1817640794169847E+003 7 3 -0.29205368674922E+01 0.1404112602437623E+002 7 4 -0.29204177603800E+01 0.7328995342445310E+002 7 5 0.33364740729340E+01 0.1817640794169847E+003 8 3 -0.29205368674922E+01 0.1404112602437623E+002 8 4 -0.29204177603800E+01 0.7328995342445310E+002 8 5 0.33364740729340E+01 0.1817640794169847E+003 9 3 -0.29205368674922E+01 0.1404112602437623E+002 9 4 -0.29204177603800E+01 0.7328995342445310E+002 9 5 0.33364740729340E+01 0.1817640794169847E+003 10 3 -0.29205368674922E+01 0.1404112602437623E+002 10 4 -0.29204177603800E+01 0.7328995342445310E+002 . . . ====================================================================
In our case, for scattering rates, we have a real part of the energy and an imaginary part of the energy, so we do the following:
We always plot real in the x-axis and imaginary part in the y-axis, Dear Sylvester Makumi
As in the paper you had pointed out, Imag part scattering cross-section ~ τ-1 in te figures "Fig. 1: Calculated scattering rates" of that paper.
Best Regards.
Hey P. Contreras,
Thank you for your answer. However, I don't get you clearly. I have attached the format of scattering rates I got from EPW. In reference to this, which are the real and imaginary parts?
Dear Sylvester Makumi
You have two variables in your data: Inverse scattering time & Energy scattering rate:
try the following:
- E scattering rate in the x-axis.
- Inverse scattering time in the y-axis.
It should work that way. The real part of the scattering cross-section goes to the x-axis and the imaginary part goes to the y axis.
Best Regards.
Thank you P. Contreras.
In Gnuplot, using "plot 'scattering' using ($3):($4) w p" I got the attached graph which looks quite different. Is this the correct procedure?
