作为半导体铁电体的六方晶系$ABC$

Hexagonal $ABC$ as semiconducting ferroelectrics

Joseph W. Bennett, Kevin F. Garrity, Karin M. Rabe, David Vanderbilt

摘要:

我们使用第一性原理的合理设计方法,以确定一个以前未被识别的类铁电材料的$P63mc$ LiGaGe结构类型。我们计算结构参数,极化和铁电阱深度报告和迄今为止假设的代表这一类。我们的研究结果为实验实现和进一步研究适合实际应用的高性能材料提供了指导。

英文摘要:

We use a first-principles rational-design approach to identify a previously-unrecognized class of ferroelectric materials in the $P63mc$ LiGaGe structure type. We calculate structural parameters, polarization and ferroelectric well depths both for reported and as-yet hypothetical representatives of this class. Our results provide guidance for the experimental realization and further investigation of high-performance materials suitable for practical applications.
