WebDec 15, 2024 · Let us now study the fcc lattice using a tight-binding approach whose Hamiltonian is only a part of the traditional one. In fact, we consider two sublattices, A and B as in Fig. 1, and only keep the tight-binding hopping terms that connect atoms of different sublattices. We begin by writing the Hamiltonian in Eq.
