the in plane lattice parameter is determined by the bulk.
the atomic positions are determined by relaxation.
beware of the possibility of surface reconstruction, especially for
semiconductors.

Hello all,
I'm studing The LiF(001) fcc structure.how to choose the lattice
parameter?? is it the same of the bulk ????
Best regards.
