Figure 3.

Top view of calculated graphene/BNC/graphene structures (top) and contour plots showing difference between up-spin/down-spin charge-density distributions (bottom). White, gray, and black circles represent C, B, and N atoms, respectively. Rectangle in each figure denotes the supercell. In the contour plots, positive values of spin density are indicated by solid lines and negative values by dashed lines. Each contour represents twice or half the density of the adjacent contour lines. The lowest contour represents 4.88 × 10−2e/bohr3.
