PtTe2 interface engineering for enhanced near‐infrared photoresponse in black silicon photodetectors
Highly responsive near‐infrared (NIR) photodetectors are essential for advanced photoelectric systems. In this work, a high‐responsivity NIR photodetector is developed by integrating a PtTe2/black silicon (B‐Si) heterostructure into a Si p‐i‐n diode, where B‐Si introduces sub‐bandgap defect states to enhance NIR absorption and the PtTe2 layer induces ...

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Nano‐Raman Spectroscopy of Tellurium Nanowires
Nano‐Raman evidences a diameter dependence of the peak position, among different tellurium nanowires and along the single species. ABSTRACT Tellurium‐based nanowires are interesting structures for applications in low‐dimensional electronics. This work investigates the vibrational dynamics of trigonal tellurium (t‐Te) nanowires through tip‐enhanced ...

We propose an UV photobleaching pretreatment to reduce the strong luminescence in the Raman spectra of plastic samples. Our protocol proves its efficiency whatever the luminescence origin (from the pigments or from a surface biofilm) but requires a careful optimization of the illumination conditions (UV wavelength, time, humidity) to reach the ...

Germanium‐Based Mid‐Infrared Integrated Photonics
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Te@Se core–shell heterojunction quantum dots (QDs) are synthesized by a two‐step strategy via combining liquid‐phase exfoliation and epitaxial growth. As active materials in photoelectrochemical photodetectors, Te@Se QDs exhibit excellent photo‐response performance in low‐concentration electrolytes and deionized water.

Responsive Phase Gradient Metasurface for Laser Stealth and Dynamic Thermal Camouflage
The graphical abstract depicts a phase‐gradient metasurface enabling directional scattering and emissivity‐controlled thermal radiation. The engineered phase profile redistributes the reflected optical momentum, suppressing specular reflection and generating non‐specular scattering.
