Post Intervalley scattering - can it be calculated in EPW?
Dear all,

I have calculated the line-widths and scattering rates (SERTA) for a semiconductor and the values are pretty reasonable. I was just wondering if there is a way to calculate the scattering rates between valleys, e.g. conduction band M > Gamma as my experiment used excitation energy in excess of the band-gap and most likely populates the M state before "cooling" to Gamma.

Any hint is very much appreciated!

Best,
Chris

Dear Chris,

All scatterings are included by default.

Are you asking about considering only those transitions ?

If this is the case, its more difficult. You probably need to print all the transitions and then only selects the one you care about.

Best,
Samuel
