In preparation to setting up this calculation, we had done a 3D bulk calculation for hcp Ru to determine the bulk lattice parameters (using the cell optimization capability of the code) using the same flavor of density functional theory we will be using for the slab calculations, the Perdew/Zunger parameterization of the Ceperley/Alder electron ... The lattice constant, or lattice parameter, refers to the physical dimension of unit cells in a crystal lattice. Lattices in three dimensions generally have three lattice constants, referred to as a, b, and c. However, in the special case of cubic crystal structures...The equilibrium lattice parameters for HCP-Hf are found to be a ¼ 3.205 Å and c ¼ 5.066 Å, giving c/a ¼ 1.581, and 9.949 eV for the cohesive energy. These values are in good agreement with experimental measurements. In the meantime, the FCC phase of Hf was also studied.

Accordingly, in this work, fcc and hcp lattice constants were measured at room and elevated temperatures in a Co-27Cr-5Mo-0.05C alloy using “in-situ” X-ray diffraction techniques. It was found that the lattice parameters corresponding to both the fcc and hcp phases increase linearly with temperature as a result of thermal expansion.
