Figure 5

Scanning tunnelling microscopy images of the nanoscale assembly of MBB-3 on different substrates: (a) on highly oriented pyrolytic graphite (height channel) and (b) on graphene over SiO2 (current channel). The images were recorded by using the following tunnelling parameters: (a) Vt=−400 mV, It=20 pA; (b) Vt=600, It=60 pA. The effect of the SL formed by MBB-3 on the electrical characteristics of a graphene device is shown in c. IDS is the drain current, and VGS is the gate potential.
