S. Chung and co-workers develop a smart strategy for a highly color-selective polymer photo diode, on page 1933.By introducing a nonabsorbing acceptor, the absorption spectrum of the color-selective donor can be fully reflected at the spectral response of the fabricated photodiodes.Furthermore, they adopt a planar heterojunction device architecture to optimize fast temporal response and low dark current.As a result, a high detectivity and narrow-band blueselective photodiode is realized. Plasmonic MetasurfacesA new type of atomically thin metasurfaces known as graphene moiré metasurfaces is developed by D. Akinwande, Y. Zheng, and co-workers.Consisting of a large number of graphene nanostructures of variable shapes and sizes in quasiperiodic arrays, the graphene moiré metasurfaces exhibit multiple resonance modes in mid-infrared regime.The tunable graphene moiré metasurfaces presented on page 2035 are fabricated by cost-effective and scalable moiré nanosphere lithography.Entering its second decade as a top tier materials science journal, Advanced Functional Materials reports breakthrough research in all aspects of materials science, including nanotechnology, chemistry, physics, and biology.Read More
