  One of the most wanted features of holography in its condensed matter physics
application is to encode the structure of lattice, which is the most direct
data of the material. In this paper, we propose a method to encode the lattice
structure by embedding the tight binding data into the Dirac equation in the
AdS bulk. We explicitly worked out the idea for the Graphene and Haldane model,
and the result shows that some degrees of freedom escape the free-electron
on-shell curve, and Green's function loses the pole structure completely. It
implies that the electronic structure is not described by the band structure
only, which is consistent with what many ARPES data tell us, and it also
implies that the system is in non-fermi liquid even for the graphene, which is
consistent with recent experiments for the clean graphene.
