Design and implementation of a full analogue gate driver for current compensation of paralleled SiC‐MOSFETs

IET Power Electronics
Silicon carbide MOSFETs have current ratings that are not sufficiently high to be used in high‐power converters. It is necessary to connect several MOSFETs in parallel in order to increase current capabilities.

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights
