Hexagonal ABC as semiconducting ferroelectrics
Abstract
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.
