Cool windows: simultaneously engineering high visible transparency and strong solar rejection
Yeonghoon Jin, Seungwon Kim, Tanuj Kumar +2
For window applications in hot climates, it is desirable to have windows with high visible transparency, while maintaining strong reflectance in both the ultraviolet and near infra…
Preventing overfitting in infrared ellipsometry using temperature dependence: fused silica as a case study
Shenwei Yin, Jin-Woo Cho, Demeng Feng +6
Fitting oscillator models to variable-angle spectroscopic ellipsometry (VASE) data can lead to non-unique, unphysical results. We demonstrate using temperature-dependent trends to…
Passive radiative cooling using temperature-dependent emissivity can sometimes outperform static emitters
Yeonghoon Jin, Jin-Woo Cho, Mikhail A. Kats
In passive sky-facing radiative cooling, wavelength-selective thermal emitters in the atmospheric transparency window of 8-13 m can reach lower temperatures compared to broadba…
A gradient atmospheric model reveals enhanced radiative cooling potential and demonstrates the advantages of broadband emitters
Yeonghoon Jin, Mikhail A. Kats
Passive radiative cooling toward the sky is a developing technology for adaptation in hot climates. Previous calculations of cooling performance have generally used uniform atmosph…
Large tuning of the optical properties of nanoscale NdNiO3 via electron doping
Yeonghoon Jin, Teng Qu, Siddharth Kumar +6
We synthesized crystalline films of neodymium nickel oxide (NdNiO3), a perovskite quantum material, switched the films from a metal phase (intrinsic) into an insulator phase (elect…
