Figure 4From: Electronic and transport properties in circular graphene structures with a pentagonal disclinationLocal density of states for E = 0. Spatial distribution of the local density for ρ(i,E) for the energy E close to zero in (a) a structure with no defect and (b) one with the pentagonal defect in the centre. Due to single-bond atoms (see Figure1), the quantum dot is not fully symmetric around a central vertical axis.Back to article page
