Metal Alloys for Superabsorption: Lithography-Free, Omnidirectional, CMOS-Compatible AlCu Alloys for Thin-Film Superabsorbers (Advanced Optical Materials 2/2018)
Zackery A. Benson, Mariama Rebello Sousa Dias, Marina S. Leite, Chen Gong
Complementary metal–oxide–semiconductor (CMOS)-compatible metal alloys formed by earth-abundant materials can enable near-unity absorption (>99%) in the visible to near-infrared spectral region. In article number 1700830, Marina S. Leite and co-workers demonstrate that Si/AlCu produces multi-wavelength, omnidirectional superabsorption in a thin-film configuration, outperforming its pure metal constituents and other metals, such as Ag and Au. Metal alloys can be potentially implemented as active elements in photonic devices.
