Transition from conventional ferroelectricity to ion-conduction-like ferroelectricity
Yuanhang Yan, Menghao Wu
The cross-unitcell long displacements in some recent emergent ferroelectrics have actually challenged the classical definition of ferroelectricity, while the relative explorations…
Robust Ferroelectricity in Silicon Dioxide upon Intercalation of Ammonia
Yaxin Gao, Menghao Wu, Jun-Ming Liu
The nanoelectronic applications of current ferroelectrics have been greatly impeded by their incompatibility with silicon. In this paper we propose a way to induce ferroelectricity…
Ferroelectric control of antiferromagnetism via coordination swapping in A2Mo3O8 (A= Mn, Fe, Co)
Yaxin Gao, Sha Li, Menghao Wu
Transition metal molybdenum oxides A2Mo3O8 (A= Mn, Fe, Co) are known to be polar magnets where A ions are located in either octahedrally or tetrahedrally coordinated sites. In this…
Unprecedented superionicity of ultra-low barrier in A0.5CoO2 (A=Li, Zn)
Xuechen Wang, Yaxin Gao, Menghao Wu
The ion conductivity of a solid-state ion conductor generally increases exponentially upon reduction in ion migration barrier. For prevalent cathode material LiCoO2, the room-tempe…
