High-aspect-ratio crack-free microstructures fabrication on sapphire by femtosecond laser ablation

, 2020
We report a novel laser processing strategy to realize high-aspect-ratio crack-free microstructures fabrication on sapphire substrates by combining femtosecond laser-induced plasma-assisted ablation and subsequent direct laser ablation. The laser-induced

Controlled Collapse of High‐Aspect‐Ratio Nanostructures

Small, 2011
AbstractCapillary‐force‐induced collapse of high‐aspect‐ratio (HAR) micro‐ and nanostructures is common in the evaporation–drying process and a number of applications based on the collapse have been proposed. However, the collapse of small HAR structures is usually uncontrollable, which has prevented it from being used in engineering applications. Here,
