Unraveling Band‐Tail Effects on Temperature‐Dependent Emission in GaAsBi via Photoluminescence

open access: yesAdvanced Science, EarlyView.
An innovative dual‐spectroscopy approach resolves the debate over GaAsBi's emission temperature sensitivity. By combining temperature‐dependent photoluminescence and transmission spectroscopy, the method decouples the contributions of band‐tail states from the intrinsic band‐edge behavior.

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
