Heterointerface‐Functionalized Photoelectric Response of Metal‐Oxide Schottky Photodiode for Intelligent Fire Detection

Advanced Science, EarlyView.
A heterointerface‐functionalized Schottky photodiode (HF‐SPD) is developed to explore the photoelectric capabilities of low‐temperature oxide semiconductors. Besides the remarkable UV detection capability, the bias‐tunable photo response endows HF‐SPD with the unique wavelength selectivity.

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

Advanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

High‐Resolution Multispectral Photovoltaic Imagers from Visible to Short‐Wave Infrared

Advanced Science, EarlyView.
We demonstrate a monolithic quad‐spectral imager that seamlessly integrates visible and short‐wave infrared detection on a single chip. Through direct photopatterning of an all‐polymer bulk heterojunction and colloidal quantum dots, the device achieves high‐resolution (640 × 512) imaging across 350–2400 nm, enabling multispectral capture for ...

Observation of Edge‐Confined Acoustic Hyperbolic Polaritons in van der Waals Materials

Advanced Science, EarlyView.
This work demonstrates a new type of light wave—edge‐confined acoustic hyperbolic polaritons—in hexagonal boron nitride on gold. These waves travel along crystal edges with nanoscale confinement and strongly interact with molecular vibrations, enabling highly sensitive detection of tiny molecular layers.
