Opals as Colorful Radiative Coolers
Hyeon Ho Kim, Eunji Im, Seungwoo Lee
Radiative cooling has proven to be a powerful strategy for sustainable thermal management. Nanophotonic structures enabling broadband reflection lead to minimization of sunlight ab…
Plasmonic Metamaterial Perovskite Solar Cells: Fundamental Tradeoffs, Limitations, and Opportunities
Kwangjin Kim, Seungwoo Lee
Whether dispersal of plasmonic nanoparticles (NPs) within a perovskite active layer can increase the efficiency of solar cells is a long-standing question. It is well known that in…
Practical Limits of Achieving Artificial Magnetism and Effective Optical Medium by Using Self-Assembly of Metallic Colloidal Clusters
Kwangjin Kim, Ji-Hyeok Huh, Doyoung Yu +1
The self-assembly of metallic colloidal clusters (so called plasmonic metamolecules) has been viewed as a versatile, but highly effective approach for the materialization of the me…
Using highly uniform and smooth Selenium colloids as low-loss magnetodielectric building blocks of optical metafluids
YongDeok Cho, Ji-Hyeok Huh, Kyung Jin Park +3
We systematically analyzed magnetodielectric resonances of Se colloids for the first time to exploit the possibility for use as building blocks of all-dielectric optical metafluids…
Assembly of 3D plasmonic metamolecules by 2D AFM nanomanipulation of highly uniform and smooth gold nanospheres
Kyung Jin Park, Ji-Hyeok Huh, Dae-Woong Jung +7
Atomic force microscopy (AFM) nanomanipulation has been viewed as a deterministic method for the assembly of plasmonic metamolecules because it enables unprecedented engineering of…
Electrical Control of Broadband Terahertz Wave Transmission with Two-Terminal Graphene Oxide Devices
Seungwoo Lee, Kyung Eun Lee, Won Jun Lee +4
Carbon nanomaterials such as carbon nanotubes and graphene have proved to be efficient building blocks for active optoelectronic devices. Especially, the exotic properties of cryst…
Colloidal superlattices for unnaturally high-index metamaterials at broadband optical frequencies
Seungwoo Lee
The recent advance in the assembly of metallic nanoparticles (NPs) has enabled sophisticated engineering of unprecedented light-matter interaction at the optical domain. In this wo…
Design of Optical Metamaterial Mirror with Metallic Nanoparticles for Broadband Light Absorption in Graphene Optoelectronic Devices
Seungwoo Lee, Juyoung Kim
A general metallic mirror (i.e., a flat metallic surface) has been a popular optical component that can contribute broadband light absorption to thin-film optoelectronic devices; n…
Efficient Confinement of Ultraviolet Light into the Self-Assembled, Dielectric Colloidal Monolayer on a Flat Aluminum Film
Seungwoo Lee, Juyoung Kim
Here we propose the efficient confinement of ultraviolet (UV) light into the plasmonic-photonic crystal hybrid, which can be practically developed by the self-assembly of dielectri…
