Figure 1.

Calculated atomic structure of diamond C(331) surface with graphene-like stripes. (a) The dashed lines indicate the supercell viewed from the direction. The large circles denote the C atoms, and the small circles denote the H atoms. (b) The dashed box indicates the supercell viewed from the [331] direction, and the bottom is viewed from the direction. The large circles denote the C atoms of the graphitic layer, and the smaller circles indicate the sp³-bonded C atoms in the outmost surface. The other C and H atoms are represented by the smallest circles.
