Fig. 2

(A) Raw HRTEM image showing the interpenetrating graphene networks with long-range disorder and short-range order (also see fig. S3). The local order has a lateral dimension of 1 to 5 nm and exhibits lattice spacings of 3 to 5 Å. (B) Schematic linkage types between the graphene layers. The layers are distinguished by different colors, that is, light and dark gray, respectively. Under pressure, the sp3 bonds colored by yellow are readily formed at the curved surfaces of graphene layers with different orientations (top) and are also easily formed between the interlayers (center). In addition, orderly buckled graphene sheets would form the short-range ordered carbon nanolattice (bottom).
