Figure 3: Effect of supramolecular lattices onto the electrical characteristics of graphene.
(a,b) Electrical characteristics of a clean device and of the same device after the formation of MBB-1 (a) and MBB-2 (b) supramolecular lattices. IDS is the drain current, and VGS is the gate potential. (c,d) Zoom of the optimized supramolecular lattice at the functional head groups for (c) MBB-1 and (d) MBB-2. In c,d, the position of the CF3 groups is highlighted by a black circle. Carbon atoms are shown in grey, hydrogen in white, oxygen in red, nitrogen in dark blue, fluorine in light blue and chlorine in green. As a scale reference, the distance between adjacent carbon atoms in the graphene substrate is 1.4 Å.
