SEM images of flower-like and grass-like architectures. Flower-like architectures grown on (a) unpolished Cu foil specimen, (b) Cu foil specimen polished using a 400-grit abrasive paper, and (c) Cu film specimen heated at 120°C for 2 h, respectively. Grass-like architectures on (d) unpolished Cu foil specimen, (e) Cu foil specimen polished using a 400-grit abrasive paper, and (f) Cu film specimen heated at 240°C for 2 h, respectively.
