CW‐Pumped Amplified Spontaneous Emission From Thermally Evaporated CsPbBr3 Films

Advanced Science, EarlyView.
Thermally evaporated CsPbBr3 thin films sustain amplified spontaneous emission from short‐pulse toward quasi‐continuous‐wave excitation. Time‐resolved spectroscopy, controlled excitation, and substrate engineering reveal how excitation duration governs optical‐gain stability.

Ultra‐Low Power Consumption and Highly Durability in Sm:HfO2 Thin Film Ferroelectric Memristor for Edge Detection

Advanced Electronic Materials, EarlyView.
ABSTRACT With the continuous development of computer image processing, developing efficient and low‐power computing devices has become a key challenge. Memristors have integrated in‐situ storage and computing capabilities, making them an ideal choice for low‐power image processing computing architectures. However, current memristors are confronted with

Anion‐Cation Synergistic Passivation for High‐Performance FA‐Cs Halide Perovskite Photodetectors

Advanced Electronic Materials, EarlyView.
An anion‐cation synergistic passivation strategy is developed to improve perovskite photodetectors. Surface‐localized DMePDA2+ cations and bulk‐diffused Cl− anions simultaneously reduce defects, enhancing charge transport and suppressing recombination.
