Figure 2From: The fabrication of large-scale sub-10-nm core-shell silicon nanowire arraysSchematic depiction of the assembly of monolayer PS sphere arrays. (a) Pretreated glass in the center of the petri dish, (b) adding water, (c) adding PS sphere mixture, (d) waiting for the water to immerse the glass, (e) adding surfactant, (f) elevating the water surface, (g) pulling the glass to the edge of the petri dish and putting a piece of silicon wafer on it, (h) pushing the glass and silicon wafer to the PS sphere side altogether, and (i) withdrawing the excess water.Back to article page
