Imperfection in Semiconductors Leading to High Performance Devices

Advanced Science, EarlyView.
Crystalline perfection is typically pursued in semiconductors to enhance device performance. However, through modeling and experimental work, we show that defects can be strategically employed in a specific detection regime to increase sensitivity to extreme values. GaN diodes are demonstrated to effectively detect high‐energy proton beams at fluxes as

TP53BP2 Promotes Placental Autophagy and Preeclampsia via G9a and DNMT1 Cooperatively Modulating E2F1

Advanced Science, EarlyView.
G9a, and DNA Methyltransferase1 (DNMT1) cooperatively modulates E2F1 on the promoter of tumor suppressor p53‐binding protein 2 (TP53BP2) increased autophagy in preeclampsia. TP53BP2 promotes autophagy in trophoblasts through DNA methylation and H3K9me2‐mediated transcriptional regulation.

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

Advanced 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

Multi‐Soliton Microcombs Enable Ultrafast Nanometric‐Precision Ranging and Photon‐Level Detection

Advanced Science, EarlyView.
Our work first demonstrates dual‐multi‐soliton ranging and confirms its multifunctional capability. The method achieves ultrafast and nanometric‐precision measurement. For practical applications, we further extend the multi‐soliton states to photon‐level ranging.

Ultrafast Nonlinear Dynamics of Indium Tin Oxide Nanocrystals Probed via Fieldoscopy

Advanced Science, EarlyView.
The ultrafast nonlinear dynamics of indium tin oxide nanocrystals excited with 1 MHz, 10 fs pulses, at their localized surface plasmon frequency, and near their epsilon‐near‐zero wavelength is probed via fieldoscopy. The study demonstrates fluence‐dependent switching behavior, advancing the understanding of high‐speed optical modulation in plasmonic ...
