Advanced Science, EarlyView.This work demonstrates a paradigm‐shifting strategy to simultaneously achieve broadband wavelength tunability and single‐mode control within a single perovskite microwire structure. Using a facile heating‐assisted solid–solid anion‐exchange strategy, we synthesized phase‐pure CsPbClxBr3‐x microwires that exhibit the widest reported continuous lasing ...

Advanced Electronic Materials, EarlyView.A diagnostic method for reconfigurable intelligent surfaces (RIS) based on non‐uniform space‐time‐coding modulation is presented. Fault localization is achieved via amplitude‐only spectral measurements, eliminating the need for complex signal processing. A one‐to‐one mapping between harmonic components and RIS elements enables accurate detection.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Photoresponse Properties of Ambipolar Transport in WSe2 Field‐Effect Transistors
Advanced Electronic Materials, EarlyView.This study explores the photoresponse of WSe2 ambipolar field‐effect transistors, which exhibit unipolar, saturation, and ambipolar transport regions. Light illumination induces a shift of critical voltage with enhanced photocurrent generation driven by the photogating effect without the material degradation seen in avalanche photodetectors. This study
