We report the extraordinary light harvesting property of a metamaterial-based subwavelength nanopillar array with a periodic arrangement. It is found that the meta-nanopillar array can absorb light efficiently with an average absorptivity of 0.96 ov

HYBRID NANOPILLAR FORESTS WITH BROADBAND HIGH ABSORPTANCE

Angle tolerant transmissive subtractive color filters incorporating a metasurface exploiting hydrogenated amorphous silicon nanopillars (NPs) on a glass substrate were proposed and demonstrated. The achieved transmission efficiency ranged from 75% to

Hybrid structures of Fe3O4 and Ag nanoparticles on Si nanopillar arrays substrate for SERS applications

Incipient plasmonic bubble formation is observed around gold nanopillars with different inter-nanopillar separations. The experimental measurements and theoretical analysis show that the nanobubble formation is due to the enhanced plasmonic resonance
