Some challenges in creating such a free-standing atomic chain using a controlled STM technique are addressed by Tartaglini and co-workers [29]. These atomic chains are ideal

This causes a single linear bond to become comparable to three bonds (for gold) in the bulk. Since our MD simulation uses

This was demonstrated in experiments by making length histograms [8] of conductance and it was observed as oscillations in conductance. However, in this method averaging over many atomic

• from the other edge. If the constriction is narrow enough to promote coupling between edges, it gives rise to Fano-like resonances as well as antiresonances in the transmission spectrum. These effects are shown to mimic an atomic chain like behavior in a two dimensional atomic crystal. Keywords: 2D

• the constriction width (hence the area for a fixed length) is a further indication that we are dealing with a strictly 1D effect at the edges. Albeit there is the underlying 2D crystal, the behavior revealed here is the one of an effective atomic chain. Here we should note that the only signature of
