3D woodpiles (IMAGE)
Caption
The researchers used their optimized direct laser writing approach to create high-resolution 3D woodpiles using multiphoton DLW. (a) A schematic of a 3D woodpile (b) A 45°-oblique-view SEM image of a 3D woodpile with a rod spacing of 300 nm. (c–f) 3D woodpile structures with eight layers and a footprint of 15 × 15 μm2 and insets showing the corresponding true-color reflection-mode micrographs of the structures.
