FIG. 1.

The schematic representations of the junction regions: (a) L(6,0)-T(12,0)∕3600 and (b) L(6,0)-T(6,6)∕3648. The atoms and bonds in light shade in the right and left regions represent the right junction and left junction, respectively, whose LDOS are plotted in Figs. 2 and 3.

FIG. 2.

LDOS of the right junction, the left junction, the middle portion, and the (6,0) SWCNT-contacted CNTR for the L(6,0)-T(6,6) carbon nanotorus junctions with (a) 3648 atoms and (b) 3672 atoms in the torus, respectively. LDOS of the middle portion, the left junction, and the right junction have been displaced upwards by 0.1, 0.2, and -atom, respectively: (c) DOS of SWCNTs (6,6) and (6,0) as well as CNTRI (6,6)∕3648 and (6,6)∕3672. DOSs of CNTR (6,6)∕3648, SWCNTs (6,0) and (6,6) have been displaced upwards by 0.1, 0.2, and -atom, respectively.

FIG. 3.

LDOS of the right junction, the left junction, the middle portion, and the (6,0) SWCNT-contacted CNTR for the L(6,0)-T(12,0) carbon nanotorus junctions with (a) 3600 atoms and (b) 3648 atoms in the torus, respectively. LDOS of the middle portion, the left junction, and the right junction have been displaced upwards by 0.1, 0.2, and -atom, respectively. (c) DOS of SWCNTs (12,0) and (6,0) as well as CNTRI (12,0)∕3600 and (12,0)∕3648, respectively. DOS of CNTR (12,0)∕3600, SWCNTs (6,0) and (12,0) have been displaced upwards by 0.1, 0.2, and -atom, respectively.

FIG. 4.

Conductance of the L(6,0)-T(6,6) contacted CNTRI with (a) 3648 atoms and (b) 3672 atoms in the torus, respectively. Also shown are the conductance of the SWCNTs (6,0) and (6,6).

Image of FIG. 5.
FIG. 5.

Conductance of the L(6,0)-T(12,0) contacted CNTRI with (a) 3600 atoms and (b) 3648 atoms in the torus, respectively. Also shown are the conductance of the SWCNTs (6,0) and (12,0).
