Lattice translational vector
WebIn Fig. 1, a graphene sheet with defined chiral vector and angle may be seen. The chiral vector can be described in terms of the lattice translational indices (n,m) and the unit vectors a 1 and a 2 (see Fig. 1), as shown in Eq. (1): WebA lattice is a periodic array of points generated by translation vectors (quasiperiodic lattices are discussed separately later). As an example, consider a two-dimensional …
