[Wien] effective mass calculation from electronic band structure

[Fecher, Gerhard]

for this purpose I made my own k-lists by hand
and used the energies from the band structure (case.spaghetti_ene);
principally one can also use the case.energy files if one has a proper k-list.
What to use may depend on the format you like to have for the method you use to analyse the E(k) dependence.
(I did the analysis using Origin (checked also by MapleV))
Codes for second order derrivatives may be found in Numerical Recipes for Fortran or other books on numerical mathematics.

Ciao

Betreff: [Wien] effective mass calculation from electronic band structure

Dear wien 2k users ,
Greetings .
I am working on Heusler alloys for thermoelectric applications . During literature survey  I read a journal
Phys. Status Solidi A, 1–16 (2015) / DOI 10.1002/pssa.201532595.Gerhard H. Fecher.
In this paper author has calculated effective mass for ZrNiSn. in different directions of Brillouin zone from dispersion curve.
My doubt is that which output file I should check for corresponding value of Energy and momentum i.e k points.
Thanks all in advance.
