Fig. 5: Synthesis of 4 dimers on Ag(111).
From: On-surface synthesis of nitrogen-doped nanographene with an [18]annulene pore on Ag(111)

a STM topography of the Ag(111) surface after annealing at 300 °C for 10 min. b Close-up view of single dimer. c Constant height dI/dV map over the dimer in b, and (d) the corresponding Laplace filtered image. e Chemical structure of the dimer, 5. Measurement parameters: V = 200 mV and I = 10 pA in a. V = 200 mV and I = 5 pA in b.
