Rapid Fabrication of Periodic Patterns on Poly(styrene-co-acrylonitrile) Surfaces Using Direct Laser Interference Patterning

Figure 4

(a) Typical histogram (calculated from SEM image depicted in Figure 3(c)) of the holes areas, together with the distribution of holes areas in the SEM image. (b) Dependence of the maximum of hole area distribution obtained from the histograms like the one shown in Figure 4(a) on the copolymer feed ratio, at different fluences (stated in the figure).
