AI Summary

Laser‑induced dewetting turns continuous ultrathin gold films into nanoscale islands when heat or laser light destabilizes the film. This process offers higher precision, speed, and flexibility than thermal dewetting, making it attractive for patterning metallic films. However, controlling the size and distribution of the resulting nanostructures is difficult, limiting its use in plasmonic color printing and metasurface fabrication. In other applications, such as low‑emissivity window coatings and nanoscale plasmonic devices, dewetting is undesirable because it shortens coating life and degrades performance.
