Figure 7.

(A) 9 × 9 array of np-Au patterns on single 20 mm silicon chip. Each column contains 9 identical squares spaces 1 mm apart with each row decreasing height and width by 100 μm starting at 1 mm height and width (far left) and decreasing to 200 μm height and width (far right). (B) Top-view SEM images of each photothermally annealed np-Au morphology on the np-Au material library. (C) Ligament width analysis demonstrates a roughly linear increase in ligament width as laser irradiance is increased. (D) Pore area analysis demonstrates a clear increase in pore size with increasing laser powers, with distributions becoming less dominantly distributed towards smaller pore areas. Red dashed line denotes median value for both ligament width and pore area distributions and the surrounding shaded region corresponds to the standard error.
