Femtosecond Laser Induced Nanowire Technique and Its Applications
Figure 4
SEM images of nanowires. The arrow shown in (a) was the seed of nanowire. The number of laser shots were 100 times for (a), 500 times for (b), 1500 times for (c), and 2500 times for (d). The laser power was 18 μJ at 800 nm wavelength.
