Perovskite Metamaterials

Conference on Lasers and Electro-Optics, 2016
We report the first dielectric metamaterials nanostructured from solution-processed organolead halide perovskite thin films. Metamaterials exhibit strong resonances tunable by design across the visible spectrum, aiming applications in enhanced photovoltaics and light-emitting devices.
