Figure 1

The illustration of experimental procedure to obtain large-area, highly-ordered single crystal arrays.

(a) A tiny slope is generated by inserting a small piece of coverslip under the corner of the substrate. Then, the setup is kept at a desired temperature for rapid evaporation of the solvent. Finally, the solution is dropped on the substrate directly by a burette until the solution covers the substrate completely (about 70 μL). (b,c) As the solvent evaporates quickly, the solution recedes along the slope direction rhythmically, resulting in the formation of ordered single crystal arrays. (d) The well-aligned single crystal arrays are obtained on the whole substrate surface in the large area.
