Abstract:

We investigate the coherent electronic transport properties of square-shaped zigzag graphene nanoconstrictions (ZGNC) under transverse strain using recursive Green’s function method. We find that the low-bias conductance of ZGNCs is monotonically dependent on the strain in contrast to that of zigzag graphene nanoribbons (ZGNRs), which is unaffected by strain. This result suggests that ZGNCs can be used as elementary building blocks in graphene nanomechanical system devices. In addition, a simplified analytical model is employed to qualitatively explain the strain tuning of the low-bias conductance of ZGNCs.
