My system is 2x2x2 ZnO supercell with 32 atoms. The lattice parameters of unit cell of ZnO are a=b=3.2495 angstrom and c=5.2069 angstrom. My question is should I multiply the lattice parameters by 2 when I perform a scf calculation for my system?</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;">Regards,</div><div
