Quasi-three-dimensional hierarchical topography. a Schematic diagram of the fabrication process. b SEM images from top (right) and cross-sectional (left) view of the nanodots film and three typical quasi-three-dimensional hierarchically topographies with controlled density of nanorods. c Quantitative analysis of the density, diameter, height as well as the percent of nanorods area of the three topographies (n ≥ 10)
