Silicon (Si) and Germanium (Ge) crystallize in the diamond cubic structure. This structure is essentially a Face-Centered Cubic (FCC) lattice with a two-atom basis. Using the dynamical matrix approach, we can extend the 1D concept to 3D. The dispersion relation $\omega(\mathbfk)$ is derived by solving the eigenvalue problem: $$ \sum_j' D_jj'(\mathbfk) e_j(\mathbfk) = \omega^2 e_j(\mathbfk) $$ Where $D$ is the dynamical matrix constructed from force constants.
