Aug 29, 2018 2.1. Basics of graphene structure. Carbon is the sixth element in the periodic table, with a ground-state electronic configuration of 1s 2 2s 2 2P x 1 2P y 1 2P z 0, as shown in Figure 2(b).For convenience, the energy level of 2p z is kept with no electron, though it is equivalent to the energy levels of 2p x and 2p y.As seen in Figure 2(a), the nucleus of a
