Honeycomb lattices Honeycomb lattice (or hexagonal lattice) is realized by graphene. The lattice consists of two carbon atoms (hereafter we call them A and B sites) per unit cell. The lattice vectors can be written as a1=a2(3,3),a2=a2(3,3), where a denotes carbon-carbon distance. The corresponding reciprocal lattice vector..
