摘要

压电性氮化铝钪（AlScN）在极端温度下表现出显著的铁电性、压电性和介电稳定性。在2400849号文章中，Roozbeh Tabrizian及其同事展示了高达1000°C的TaSi2/AlScN/TaSi2电容器的稳健性能，揭示了压电性的大幅增加和矫顽力场的显着降低。这些发现使AlScN成为空间、高超声速、深井和核反应堆应用的关键功能材料。

Piezoelectrics

Aluminum scandium nitride (AlScN) exhibits remarkable ferroelectric, piezoelectric, and dielectric stability at extreme temperatures. In article number 2400849, Roozbeh Tabrizian and co-workers demonstrate the robust performance of TaSi₂/AlScN/TaSi₂ capacitors up to 1000 °C, revealing a substantial increase in piezoelectricity and a marked reduction in coercive field. These findings establish AlScN as a key functional material for space, hypersonics, deep-well, and nuclear reactor applications.
