Pulsed light aided thin film de-wetting process to fabricate nano-patterned array is introduced. Being compared to thermal annealing process, highly intense pulsed light with millisecond duration plays a role to transform solid-state thin-film to metastable and provides enough energy as a driving force to form island-like pattern. Topological analysis using SEM and AFM was performed to confirm fabricated structures. In addition, optical performance regarding surface-plasmon resonance and light absorption was studied by experimental UV-VIS spectroscopy and computer aided electromagnetics (EM) simulation. This research will benefit to the real-time roll-to-roll fabrication for the fabrication of nanostructures without using of thermal soaking and vacuum process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
