Formation, Energetics, and Electronic Properties of Graphene Monolayer and Bilayer Doped with Heteroatoms

Figure 9

Work functions of pristine and B(N-) doped (a) monolayer with the substitutional B (SB), the substitutional N (SN), the trimerized pyridine-type (P3), and the tetramerized pyridine-type (P4) defects and (b) bilayer graphenes with AA, AB1, and AB2 stacking. The horizontal broken lines denote pristine monolayer and bilayer graphenes. (b) is taken from [57]. Reproduced with permission from [57], copyright 2015, Elsevier.
