Study Findings from Shanghai Institute of Technical Physics Broaden Understanding of Nanoparticles (Vapor-deposited amorphous metamaterials as visible near-perfect absorbers with random non-prefabricated metal nanoparticles)

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Nanoparticles have been published. According to news reporting from Shanghai, People's Republic of China, by NewsRx journalists, research stated, "Spatial order or periodicity is usually required and constructed with tens of nanometers in the feature size, which makes it difficult to process the near-perfect metamaterial absorbers (PMAs) working in the visible range in large-area and mass-production scale. Although many established technologies and theoretical modeling methods used for order-based metamaterials, aperiodic or disordered structures have been gradually recognized to achieve similar functionalities for which the ordered structures are overwhelmingly used."

The news correspondents obtained a quote from the research from the Shanghai Institute of Technical Physics, "Here, we demonstrated the vapor-deposited 'amorphous' metamaterials as controlled-reflectance surfaces and tunable PMAs without the use of the lithographically ordered arrays, the prefabricated colloidal metal nanoparticles (MNPs) or the multilayer of nanoparticles. The flexible construction, the control of the monolayer of MNPs and the atomic-layer-deposited (ALD) dielectric spacer layer provide more insight for understanding the controlled-reflectance surfaces."

According to the news reporters, the research concluded: "Such processes have a few key advantages of CMOS-compatible simple processing, low cost and large-area plating, allowing the PMAs to be flexibly constructed in mass-production scale."
