Liquid‐Crystal‐Based Reconfigurable Intelligent Surface for 7 GHz Mobile Communication

Advanced Materials Technologies, EarlyView.
The glass‐based liquid‐crystal reconfigurable intelligent surface (LC‐RIS) integrates active‐matrix driving and blind‐greedy phase optimization within a 5G‐NR OFDM framework. This enables continuously tunable and autonomous enhancement of wireless coverage. Leveraging the transparency and manufacturability of liquid crystal panels, it is ideally suited

Multilayer cryogenic powder filters with low parasitic capacitance

Review of Scientific Instruments
We report the development of a cryogenic powder filter that simultaneously offers high attenuation of radio frequency (RF) signals in the gigahertz range and minimized parasitic capacitance to ground. Conventional powder filters, which consist of a signal line passing through a metal powder-filled housing, attenuate high-frequency signals via the skin ...

Chalcogen Alloy‐Engineered Te2Se/Si Heterojunctions for Low‐Noise Complementary Metal‐Oxide Semiconductor‐Compatible Short‐Wave Infrared Imaging

Advanced Optical Materials, EarlyView.
A Te2Se/Si heterojunction designed through atomistic simulations reduces oxide‐related traps, dark current, and noise compared with pure tellurium devices. This CMOS‐compatible platform enables short‐wave infrared detection and high‐contrast imaging in a 14 × 14 array, highlighting a scalable strategy for robust, low‐noise SWIR photodetectors and image

Post‐Deposition Photonic Curing Treatment for Improved Sb2Se3 Photovoltaic Performance

Advanced Optical Materials, EarlyView.
Millisecond‐scale photonic curing overcomes the open‐circuit voltage deficit in Sb2Se3 solar cells by transforming the rear interface. This ultrafast treatment enhances crystallographic texture and smooths the absorber surface, suppressing interfacial recombination and boosting power conversion efficiency to 8.2%.
