Schematics of BC2N nanoribbons of the models A (a), B (b), C (c), and D (d). The red (blue) circles represent B (N) atoms and C atoms are located at the vertices of hexagons. The yellow-shaded dotted lines represent the unit cell of BC2N sheet of the model-I introduced in . The unit cell of BC2N nanoribbons were indicated by the dashed rectangles.
