Quantitative Analysis and Mitigation Strategy for Hot Carrier Degradation in a‐IGZO Transistor
Advanced Electronic Materials, EarlyView.This work presents a quantitative analysis of hot carrier degradation in a‐IGZO transistors, revealing an asymmetric drain‐side Schottky barrier increase and localized defect generation. The transfer length method and SCLC measurements enable defect quantification.

ChemSusChem, Volume 18, Issue 6, March 15, 2025.Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

Ecography, EarlyView.Earthworms, as ‘ecosystem engineers', play a crucial role in regulating ecosystem functions and shaping community structures. Due to climate change, earthworms face severe survival pressures and extinction risks. However, whether conservation efforts targeting aboveground biodiversity can cover the long‐neglected earthworm diversity remains unknown. To
