Impact of Rapid Thermal Annealing on the Structural and Piezoelectric Properties of AlN Thin Films

Advanced Electronic Materials, EarlyView.
Aluminum nitride (AlN) is a biocompatible piezoelectric material suitable for energy harvesting in MEMS resonators. Through rapid thermal annealing, a threshold for CMOS‐compatible processes is established. AlN improved its crystallinity and enhanced the piezoelectric coefficient by ∼160%. Devices show an improvement in the electromechanical properties

Channel‐trap coupled charge modulation in sulfur‐vacancy‐rich nanotransducer for enhanced dual‐mode cancer catalytic therapy

BMEMat, EarlyView.
Sulfur vacancy‐rich ZnS–NCx heterojunctions are engineered as dual‐function nanotransducers, in which channel‐trap‐coupled electronic pathways enable efficient capture and transport of ultrasound‐induced piezoelectrons. This vacancy‐mediated regulation simultaneously enhances sonodynamic activity and biomimetic POD/GSHOx catalysis, triggering a self ...
