| Abstract: | Basing on ab initio method and the elastic scattering Green function theory,we have investigated the electronic transport properties of 1,4-dicyanobenzene with the different distances between electrodes.Numerical results show that with different distances between electrodes the electronic transport properties have distinct differences.Namely,at the same voltage,current decreases with the increased length between electrodes. |
