Figure 4: NO adsorption.
From: Atomically controlled substitutional boron-doping of graphene nanoribbons
(a) STM topography of B-GNR with NO molecules. Blue, red and yellow arrows indicate NO molecules attached at the elbow of herringbone structure on Au(111), the armchair edge, and the boron site of the B-GNRs, respectively. Scale bar, 5 nm. (b–d) A series of STM images to show the hopping NO between the boron sites. (e) Simulated STM image. (f,g) Side and top views of calculated conformation of NO adsorbed at the boron site in B-GNR. Nitrogen, oxygen and boron atoms are shown in blue, red and green, respectively. Measurement parameters: V=−200 mV and I=1 pA in (a) and I=2 pA in (b–d).
