WebOct 15, 2024 · GNR fabricated by this method (1,20) have a uniform width but vary in length. Whereas Co on Au (111) has an apparent height of 0.1 nm in the STM images, Co adatoms on a GNR show an apparent height of 0.23 nm. A similar increase in apparent height is also observed on ultrathin insulating layers. WebFig. 3 (a) Representative STM overview image (U s = 0.5 V, I t = 40 pA) of the GNR sample after cyclodehydrogenation of the primarily (S)-polymer sample shown in Fig. 2.The inset indicates the three growth orientations of each enantiomeric polymer (red and blue arrows) with respect to the high symmetry Au(111) directions (white arrows).
