Schematics of the growth evolution of parallel CeSix NW arrays on Si(110)-16 × 2 surfaces. (a) Si(110)-16 × 2 surface. (b, c, d) Parallel arrays of 3-NW, 6-NW, and 9-NW. The upper and lower terraces on the Si(110) surface are labeled by UT and LT. The left and right zigzag chains in the 6-NWs and 9-NWs are labeled by LZ and RZ. The linear rows at the middle of the 9-NWs are labeled by MR.
