The effect of stacked graphene flakes (GFs) on the electronic transport property of zigzag-edged graphene nanoribbon (ZGNR) is investigated.By using the Green's function method,we calculate the conductances of ZGNRs with two different stacked-type GFs.It is found that the coupling effect between ZGNRs and GFs can induce dips at the conductance profiles in two different stacked-types.For both stacked-types,the dips far away from the Fermi level are nearly overlapped.However,the position of conductance dip ne...
