Organic-assisted band engineering enables high-performance self-powered solar-blind 4H-SiC photodetectors

MAOYIN WANG, Zhijian Zhang, ZHEN WANG, JIANBIN GUO et autres

Traditional metal–semiconductor–metal photodetectors (MSM) based on 4H SiC typically have relatively low zero-bias photo-response due to insufficient internal electric fields. To address this issue, we integrated a thermally evaporated p-type organic semiconductor (C8-BTBT) onto an n-type 4H-SiC MSM device to form a …

Comparative Degradation Analysis of 1200 V SiC MOSFETs With Different Gate Structures Under High Drain Bias Stress

Peng Liao, Yanghao Wang, Xiaona Ma, Jianbin Guo et autres

Silicon carbide (SiC) MOSFETs are emerging as key components in next-generation electric vehicle powertrains, owing to their superior material properties. However, under automotive harsh conditions such as load dump or inductive shutdown, the device may experience extreme drain voltage stress near or …

Stepwise Breakdown-Induced Degradation Analysis of 1200V SiC MOSFETs with Different Gate Structures

IEEE International Symposium on Reliability Physics 2026, Jianbin Guo, Peng Liao, Qingqing Sun et autres

This work investigates stepwise breakdown–induced degradation in commercial 1200V SiC MOSFETs with planar gate (PG), asymmetric trench (AT), and double trench (DT) structures. Under stepwise drain voltage stress, PG and AT exhibit hard breakdown with distinct pre- and post-breakdown stages, while DT …

Administrative-driven hierarchical management of atrial fibrillation on cardiovascular events: a prospective matched cohort study

Mu Chen, Mingzhe Zhao, Yuli Yang, Xin Cui et autres

The administrative-driven hierarchical management (ADHM) refers to the management model that general practitioners act as "voluntary gatekeepers" under local government policy incentives in the non-mandatory hierarchical medical system. However, the impact of ADHM of atrial fibrillation (AF) on cardiovascular events remains unclear. …

Temperature-Dependent Reverse-Recovery Behavior Analysis and Circuit-Level Mitigation of Superjunction MOSFETs

Wenrong Cui, Peng Liao, Yanghao Wang, Jianbin Guo et autres

This study explores the temperature dependence of reverse-recovery behavior in superjunction metal-oxide-semiconductor field-effect-transistors (MOSFETs) using experiments and Technology Computer-Aided Design (TCAD) simulations. Results show that at 145 °C, switching failure occurs due to severe reverse-recovery degradation. The main cause is the temperature-induced …
