Figure 1. Substrate Lay-out.

Figure 1

(A) The substrate consisted of individual areas decorated with pillars of different dimensions. The pillar width ranged from 1–5.6 µm (1, 1.2, 1.4, 1.6, 1.8, 2, 2.4, 2.8, 4, 5.6 µm) in the vertical direction, while the spacing ranged from 0.6–15 µm (0.6, 0.8, 1, 1.2, 1.4, 1.6, 1.8, 2.0, 2.4, 3.2, 4, 5, 7, 10, 15 µm) and the height was kept constant at 3 µm. (B) Scanning electron microscopy images of different width and spacing of pillars. Left is W = 1 µm, S = 1 µm, middle is W = 1.6 µm, S = 1.6 µm, right is W = 5.6 µm, S = 10 µm. Scale bars are 10 µm.
