Origin of Interstitial Doping Induced Coercive Field Reduction in Ferroelectric Hafnia
Tianyuan Zhu, Liyang Ma, Xu Duan +1
Hafnia-based ferroelectrics hold promise for nonvolatile ferroelectric memory devices. However, the high coercive field required for polarization switching remains a prime obstacle…
Two-dimensional multiferroic metal with voltage-tunable magnetization and metallicity
Xu Duan, Jiawei Huang, Bin Xu +1
We design a multiferroic metal that combines seemingly incompatible ferromagnetism, ferroelectricity, and metallicity by hole doping a two-dimensional (2D) ferroelectric with high…
On-demand quantum spin Hall insulators controlled by two-dimensional ferroelectricity
Jiawei Huang, Xu Duan, Sunam Jeon +4
The coexistence of ferroelectric and topological orders in two-dimensional (2D) atomic crystals allows non-volatile and switchable quantum spin Hall states. Here we offer a general…
Designing Xenes with Two-Dimensional Triangular Lattice
Xu Duan, Zhao Liu, Brendan M. Hanrahan +2
Xenes, graphene-like two-dimensional (2D) monoelemental crystals with a honeycomb symmetry, have been the focus of numerous experimental and theoretical studies. In comparison, sin…
