Schematic representation of the five nanojunction systems and group velocities for propagating band structure modes. (A) Schematic representation of the five nanojunction systems composed of silicon and carbon atoms between one-dimensional carbon leads considered in the present work. The irreducible domains are marked by the shaded grey areas, whereas for the other cases, only the irreducible domains are shown. (B) The group velocities for the propagating band structure modes on the carbon leads.
