Crystal Structure of Graphite, Graphene and Silicon

 &#; Our discussion of the crystal structure of graphite fol-lows partially from D.D.L. Chung’s review of graphite [1]. When multiple graphene sheets are layered on top of each other, van der Walls bonding occurs and the three di-mensional structure of graphite is formed with a lattice FIG.: In-plane structure of graphite and reciprocal lattice
