Dear Priya

Google is a good starting point for solving general-purpose problems: Supercells fold the unit cell band structure and make it difficult to compare with undoped band structures. If you type "unfolding supercell band structure" you find a lot of interesting tutorials. This one (among many other) might be useful to you

Dear all ,

Please bear with me ( i m newbie) .I try to dope an fcc unit cell by making
supercell of 1x1x2. So the symmetry of supercell becomes R3m while unit
cell has fm-3m symmetry so is it correct that BZ would change for my
supercell and i can no longer use the k path that is provided for fcc unit
cell.

if this is true what should i do because i would like to compare the band
structure of unitcell with supercell to see impurity effect.

I tried to read kittel and several other things but i couldn't come to any
conclusion.please help.

Thanks,
Priya
