文摘

We present a theoretical study of electron transport properties through boron-nitride aromatic molecules (BNAMs) embedded between two zig-zag graphene nanoribbons (ZGNRs), which are considered as electrodes. The work is based on a tight-binding Hamiltonian model within the framework of a generalized Green's function technique and relies on the Landauer-B¨¹tikker formalism as the basis for studying the current-voltage characteristic of this system. It is shown that the current can decrease at a finite value of voltage and the electron transport can open a conduction gap in the ZGNR/BNAM/ZGNR structure.
