Image of FIG. 1.
FIG. 1.

(a) Atomic force microscopy image of GNR and carbon nanotube. (b) and (c) Models of the unzipping carbon nanotubes for armchair- and zigzag-GNRs, respectively.

Image of FIG. 2.
FIG. 2.

Typical STM images of a single layer GNR. (a) Morphology of GNR. (b) Line profile across the GNR as marked by the blue line in (a). (c) Atomic resolved image of the same GNR in (a). The white honeycombs are lattice of GNR with zigzag edge. The comparison of the zigzag edge and the edge lines shown in (a) yields the edge direction of the GNR. The imaging conditions are 1 V, 1 nA.

Image of FIG. 3.
FIG. 3.

(a) Typical STM image of a double layer GNR. The red hexagon marks the moiré pattern caused by the relative rotation of the bottom and top lattices. (b) Constructed model according to the moiré pattern shown in (a). The model shows that the rotation angle between two lattices is .

Image of FIG. 4.
FIG. 4.

Statistical distribution of the angle between edge direction and zigzag direction of the top layer in GNRs. The square/circle/triangle symbols represent single/double/multi-layer GNRs, respectively. The arrow is a guide for eyes.
