Molecular wire making contact with a substrate at an angle . The wire in the initial form is pulled by a force to the final form . The vdW binding energy between the substrate and the wire can sustain the tension in the wire.
(Color online) (a) SEM image of long aligned SWCNTs grown across trenches. The SWCNT described in Fig. 3 is indicated by the arrow. (b) AFM image of a SWCNT grown across the 1.5, 3, and wide trenches. The SWCNT falls down to the bottom of the wide trench.
(Color online) (a) 2D integrated intensity map of the silicon peak at . The dark regions correspond to the trench regions. (b) 2D integrated intensity map of the band between 1500 and taken from a SWCNT in the same region as in (a). (c) Actual -band spectra along the length of the SWCNT shown in (b). The peak frequency of the most intense peak is observed to shift linearly with respect to the position on the substrate and remains constant across the trenches.
(Color online) (a) Schematic of a SWCNT grown across the 1.5, 3, and wide trenches. The SWCNT falls down the trench in this example. (b) with respect to position obtained from three SWCNTs (shown as black triangles, blue squares, and red diamonds) in the region shown in (a). The strain generated at propagates to the left until it completely relaxes at the points indicated by the green arrows due to the friction between the SWCNTs and the substrate.
