Influence of Electric Field in the Adsorption of Atomic Hydrogen on Graphene

Figure 8

(a) Planar projection of the chemisorption state; (b) charge density (e/ų) resulting from the subtraction of H/G charge without EF to the systems with an EF of −1.25 V/Å intensity and (c) 0.75 V/Å. The density changes are represented on a colored scale, with red and blue relating to increases and decreases, respectively.
