%X In this article we briefly overview our theoretical studies on ballistic electron transport through nanoscale junction structures by means of our first-principles electron transport calculation method based on the real-space finite difference formalism within the framework of the density functional theory. In particular, we have theoretically explored the possibility to specifically tune the electron transport properties of benzene-based molecular junctions by the physically and chemically functionalization. Moreover, we have also studied the ballistic scattering of propagating electrons at a single impurity in a Ge dimer row by employing a semi-infinite electrode system, which is more realistic than conventional periodic models.
