Single-step fabricated disordered pyramidal nanostructures for large-scale broadband visible light absorber with high-temperature stability

Laser Constructing Short‐Range Disordered Metagratings for Visible Near‐Infrared Polarization‐Independent Absorption

“…The traditional fabrication process suffers from low efficiency and high cost during the large-area fabrication of the subwavelength structures. Methods, like mask-based fabrication, [13,14] mask-free fabrication, [15,16] and composite methods, [17] are widely investigated to achieve the large-area fabrication of those broadband metasurface absorbers. Generally, multi-layers or complicated structures with an elaborated design are usually required to meet the wide bandwidth absorption demands, whose low-cost and high-efficient fabrication methods are still a long-pending challenge to overcome.A well-known light-driven self-organization phenomenon called laser-induced periodic surface structures (LIPSS) has attracted growing attention due to the advance of mask-free large-area surface patterning ability of subwavelength structures with long-range order.…”
