| Research Abstract |
This research project has covered a wide range of nanoscale materials, which have potential application in molecular electronics, such as graphene nanoribbons, nitrogen-doped capped carbon nanotubes, adamantane tripod linkage, and so on. In this report, we will present the transport properties of nanowires using the nonequilibrium Green's function approach and the density functional theory (DFT)of electronic structures using local orbital basis sets. Namely, we have investigated a relationship of the energy levels of delocalized frontier orbitals and Fermi level of metal electrodes and estimated the electronic transport properties through atomic and molecular wires.
