Figure 2.

SEM images of AAO templates and PH3T nanopillars. (a, b, c) SEM images of AAO templates with different pore diameters of (a) 80, (b) 60, and (c) 40 nm. (d, e, f) SEM images of P3HT nanopillars with diameters of (d) 80, (e) 60, and (f) 40 nm. Samples (d, e, f) were tilted by 30°. The insets show enlarged images (bar length, 100 nm).
