<div dir="ltr">Dear WIEN2k Users,<div><br></div><div>I am Abhijeet from IIT Jodhpur, India, using the WIEN2k_17.1 version. Currently, I am studying A2BB'X6 material. For the same, it is required to generate a 2*2*2 supercell. I want to substitute the B atom in
A2BB'X6
by C. The desired doping percentage are 25% C, 50%C and 75%C. </div><div><br></div><div>For 25%C and 75%C, the space group of generated supercell changed to pm-3m from fm-3m of a pristine unit cell of
A2BB'X6
. However, with 50%C in A2BB'X6
material (i.e
A2B50%B'50%X6
) case, the generated supercell exists in a very different space group of P4/mmm (tetragonal). I would like to know if both the changes i.e. "fm-3m to pm3m" and "fm-3m to P4/mmm" are okay to move on with. If not, then please suggest how to deal with it. </div><div><br></div><div>Thanks.</div><div><br></div><div>regards,</div><div>Abhijeet</div></div>
