Extended Data Fig. 1: Schematic illustration of the correspondence between the end of a wide AGNR and the edge of JGNR.
From: Janus graphene nanoribbons with localized states on a single zigzag edge
The unit cell of the AGNR, commensurate with its termination, is enclosed by an orange dashed curve. The quantities \(W\) and \({W}_{{notco}}\) in Eq. (1) are to be counted within this specific unit cell. The unit cell of the finite-size JGNR is defined by the area between two grey lines, where 1, 2, …, L label the unit cells. A sufficiently wide AGNR can always be found that shares the same termination as the edge of the JGNR. Through this mapping, the associated AGNR contains L repeated units along its width direction. The unit cell of the wide AGNR, commensurate with its termination, is the area enclosed by the orange dashed curve.
