HI Everybody
I am trying to calculate band structure of Cu2ZnSnS4 Kesterites structure, The attached file is my input file
abinit is running but doesn't give me correct results,my questions are
1. I gave it same shifts of zinc-blende structure, is that correct?
2. I gave it same sampling of k points on Brrilioun Zone of Zinc-Blende structure to draw band structure direction, is that correct?
Thanks
Nawzad

Dear Nawzad,
What do you mean by "not the correct result"?
Best wishes,
Eric

Dear Nawzad,
A few other comments, in your input you define some variables two times one without the dataset index and one with it, which might make some conflicts (kptopt and toldfe). Toldfe 1E-6 might not be enough for the SCF calculation. This might not be the source of your problem, but we never know... If this is still troublesome, please put the plot you have and specify how do you make the plot?
Cheers,
Eric
PS: I'll be away the next 10 days, not sure if someone else will reply in the meantime.
