WebThere are four common types of GNRs: armchair (AGNRs), zigzag (ZGNRs), chiral (chGNRs) and chevron (cGNRs) ones. AGNRS and ZGNRs can be uniquely identified by their width only. For AGNRs, width is typically expressed in the number of dimer lines, whereas for ZGNRs width is expressed according to the number of zigzag lines ( Fig. 1a ).
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.
