FIG. 1.

(Color online) Three types of SWCN Y junctions blocked with cluster (shown as red colored atoms). (a) (14,0)-(7,0)-(7,0) (b) (8,0)-(8,0)-(8,0), and (c) (8,8)-(8,0)-(8,0).

FIG. 2.

(Color online) Plots of the characteristics for gate potential calculated for the Y-SWCN: (14,0)-(7,0)-(7,0) connected to metal leads made of Ni either free or blocked by a Ni particle, one consisting of 16 Ni atoms and another of 32 Ni atoms. The symbols , , and denote the central (“stem”), left, and right branches of the nanotube, respectively. The upper inset shows the effect of the gate voltage (red), (green), and (blue) on of the Ni-free tube. For positive voltage there is no appreciable shift in the curves. The lower inset shows the variation , , , for as well as the variation for (dashed blue) and for the tube blocked by (green) and (violet) clusters both for .

Image of FIG. 3.
FIG. 3.

(Color online) Main figure as in Fig. 2 for the tube (8,0)-(8,0)-(8,0). The left inset shows the variation for the Ni-free tube at (solid black) and (dashed black) bias as well as for the tube blocked by (red) and (green) cluster both at bias. The right inset shows the variation , , , for as well as the variation for (dashed green) and for the tube blocked by (blue) and (violet) clusters both for .

FIG. 4.

(Color online) As in Fig. 3 for the tube (8,8)-(8,0)-(8,0).
