FIG. 1.

Side and top views of the device region of a (5,5)-tube-Au junction, where the Au electrode consists of seven atomic layers (7L). The length of the tube in the device region is and the dimensions in the lateral directions are 20.4 and , respectively. The three terminals are denoted by , , and .

FIG. 2.

Two-terminal transmission (tube to metal) for (a) (5,5)-Au and (b) (5,5)-Pd with different widths of the metal electrode, as indicated in the legends. Also plotted is the transmission for a pure (5,5) tube as a comparison.

Image of FIG. 3.
FIG. 3.

Three-terminal transmission functions , , and for (5,5)-Au [first column, (a)–(c)] and (5,5)-Pd [second column, (d)–(f)]. The width of the metal electrode is indicated in the legends. Also plotted is the transmission function of a pure (5,5) tube as a comparison (dashed). The Pd traces converge much more quickly than those for Au.

Image of FIG. 4.
FIG. 4.

Two-terminal transmission, , with semiconducting tubes: (a) Na@(10,0)-Au and (b) Na@(10,0)-Pd systems with an electrode width of 5L. The transmission function of the bare Na@(10,0) tube is shown in each panel for comparison; in addition, (a) includes for the undoped (10,0)-Au system.

Image of FIG. 5.
FIG. 5.

Three-terminal case with semiconducting tubes: , , and for (a) Na@(10,0)-Au and (b) Na@(10,0)-Pd with an electrode width of 5L. For comparison, the transmission function of the Na@(10,0) tube is also shown.
