Abstract The electronic transport properties of a molecular junction based on doping tailoring armchair-type graphene nanoribbons (AGNRs) with different widths are investigated by applying the non-equilibrium Green's function formalism combined with first-principles density functional theory. The calculated results show that the width and doping play significant roles in the electronic transport properties of the molecular junction. A higher current can be obtained for the molecular junctions with the tailoring AGNRs with $W=11$. Furthermore, the current of boron-doped tailoring AGNRs with widths $W=7$ is nearly four times larger than that of the undoped one, which can be potentially useful for the design of high performance electronic devices.
