Visualizing Strain‐Coupled Cryogenic Phase Transitions and Defect Dynamics in Perovskite Quantum Dots Using In Situ STEM

open access: yesAdvanced Science, EarlyView.
Cryogenic cooling induces an orthorhombic‐to‐monoclinic phase transition in CsPbBr3 quantum dots, accompanied by pronounced strain localization at surfaces and interfaces. Multimodal in situ STEM directly visualize reversible defect healing during moderate cryogenic treatment and irreversible degradation upon prolonged exposure, revealing the intrinsic

Two Distinct Phonon Wave Effects Control Thermal Transport across the Coherent–Incoherent Regime in Superlattices

open access: yesAdvanced Science, EarlyView.
Thermal transport in smooth‐interface superlattices is studied using the phonon Wigner transport equation, which captures both particle‐like and wave‐like contributions. A minimum in cross‐plane thermal conductivity emerges with increasing period thickness, signaling a crossover from coherent to incoherent phonon transport.

Wafer‐Scale Room‐Temperature Processing of Lead‐Free Perovskites for Optoelectronic Applications

open access: yesAdvanced Science, EarlyView.
We present the first wafer‐scale, room‐temperature synthesis of lead‐free Cs3Sb2X9 (X = Br, I) perovskite films via solvent‐free magnetron sputtering. The resulting high‐performance photodetectors achieve benchmark responsivity, bandwidth, and detectivity, enabling scalable manufacturing for next‐generation optoelectronics.
