WebJun 25, 2024 · This technique is used for two distinct types of GNRs: the 7 atom wide armchair GNR and the 3,1-chiral GNR. The features in the conductance maps can be understood and modeled in terms of the intrinsic electronic properties of the ribbons as well as capacitive coupling to tip and substrate.

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 ).
