High-aspect-ratio nanoimprint process chains [PDF]
Microsystems & Nanoengineering, 2017 AbstractDifferent methods capable of developing complex structures and building elements with high-aspect-ratio nanostructures combined with microstructures, which are of interest in nanophotonics, are presented. As originals for subsequent replication steps, two families of masters were developed: (i) 3.2 μm deep, 180 nm wide trenches were fabricated ...

Reversibly Photoswitchable High‐Aspect Ratio Surfaces
Small Structures, 2023 Herein, the fabrication of light‐sensitive high‐aspect ratio surfaces with switchable topography using melt‐electrowriting of shape‐memory polymers and deposition of light‐to‐heat converting black ink on it by dip coating is reported on. The lamellae exposed to low temperatures are hard and cannot be deformed by water droplets.
