SEM images of gold nanostripes: (a) and (b) nonannealed and (c) and (d) annealed for 5 min at 200 °C. Characteristics of the stripes shown in these images are as follows: height h = 40 nm, width w = 120 nm, length 100 μm. The SEM images (b) and (d) have been tilted with an angle of 60 degrees, allowing to give an improved perspective of the NSR features.
