Passive cooling, which cools without any electricity input, has had a great impact on global
energy consumption. The recent progress on radiative cooling has many potential …

Near-field coupling is a fundamental physical effect, which plays an important role in the
establishment of classical analog of electromagnetically induced transparency (EIT) …

The efficient amplification and lasing of electromagnetic radiation at terahertz (THz)
frequencies is a non-trivial task achieved mainly by quantum cascade laser configurations …

Hot-electron devices are emerging as promising candidates for the transduction of optical
radiation into electrical current, as they enable photodetection and solar/infrared energy …

Increasing the absorption efficiency of solar radiation has great significance for the
renewable energy applications, such as residential water heating, seawater desalination …

Despite the demands of growth, the development of deep-ultraviolet (UV) light-emitting
diodes (LEDs) still suffers from the fundamental limits of material defects and the anisotropic …

We present a new and viable template-assisted thermal synthesis method for preparing
amorphous ultrathin transition-metal oxides (TMOs) such as TiO2 and Ta2O5, which are …

Hexagonal boron nitride (hBN) exhibits natural hyperbolic dispersion in the infrared (IR)
wavelength spectrum. In particular, the hybridization of its hyperbolic phonon polaritons …

Imaging below the diffraction limit is always of public interest because of the restricted
resolution of conventional imaging systems. To beat the limit, evanescent harmonics …

Passive radiative cooling, which cools an item without any electrical input, has drawn much
attention in recent years. In many radiative coolers, silica is widely used due to its high …
