FIG. 1.

(Color online) Contact angle of gallium droplet strongly depended on the ambient temperature.

FIG. 2.

(Color online) Photo image of (a) Formvar film stretched on aluminum washer, (b) 15-nm-thick amorphous carbon film supported on aluminum washer is stable even after vacuum annealing at , (c) amorphous carbon film stamped on liquid gallium surface, and (d) film still keeps the original shape even after annealing at on liquid gallium.

FIG. 3.

TEM image of (a) gallium-treated amorphous film which was supported on copper mesh and (b) HRTEM image of the graphene stack that observed at the film folding region.

Image of FIG. 4.
FIG. 4.

Catalytic reaction induced at the gallium was strongly restricted at the interface region. Thus (a) the graphene stacking positioned in the outer side of the folding can be seen clear contrast; in contrast, (b) graphene stacking that folded in the inner side tended to be projected as weak contrast.

Typical EELS spectra of carbon-based allotropes, (a) Ga-induced graphene film, (b) graphite crystal, (c) C60, and (d) amorphous carbon film prepared by arc-discharge method.

(Color online) (a) Film is transferred on PDMS substrate adhered with liquid gallium and (b) gallium can be removed by soaking in a diluted hydrochloric acid.
