Multiferroic properties of oxygen functionalized magnetic i-MXene
Mingyu Zhao, Jun Chen, Shan-Shan Wang +2
Two dimensional multiferroics inherit prominent physical properties from both low dimensional materials and magnetoelectric materials, and can go beyond their three dimensional cou…
Ferroelectricity in strained HfCF monolayer
Ziwen Wang, Ning Ding, Churen Gui +3
Low dimensional ferroelectrics are highly desired for applications and full of exotic physics. Here a functionalized MXene HfCF monolayer is theoretically studied, which ma…
Direct Visualization of Irreducible Ferrielectricity in Crystals
Kai Du, Lei Guo, Jin Peng +12
In solids, charge polarity can one-to-one correspond to spin polarity phenomenologically, e.g. ferroelectricity/ferromagnetism, antiferroelectricity/antiferromagnetism, and even di…
Tunable anomalous Hall transport in bulk and two-dimensional 1-CrTe: A first-principles study
Si Li, Shan-Shan Wang, Bo Tai +4
Layered materials with robust magnetic ordering have been attracting significant research interest. In recent experiments, a new layered material 1-CrTe has been synthesiz…
Quadratic contact point semimetal: Theory and material realization
Ziming Zhu, Ying Liu, Zhi-Ming Yu +5
Most electronic properties of metals are determined solely by the low-energy states around the Fermi level, and for topological metals/semimetals, these low-energy states become di…
Nodal Loop and Nodal Surface States in Ti3Al Family Materials
Xiaoming Zhang, Zhi-Ming Yu, Ziming Zhu +4
Topological metals and semimetals are new states of matter which attract great interest in current research. Here, based on first-principles calculations and symmetry analysis, we…
Nonsymmorphic-symmetry-protected hourglass Dirac loop, nodal line, and Dirac point in bulk and monolayer SiTe ( Ta, Nb)
Si Li, Ying Liu, Shan-Shan Wang +5
Nonsymmorphic space group symmetries can generate exotic band-crossings in topological metals and semimetals. Here, based on symmetry analysis and first-principles calculations, we…
Hybrid Dirac Semimetal in CaAgBi Materials Family
Cong Chen, Shan-Shan Wang, Lei Liu +4
Based on their formation mechanisms, Dirac points in three-dimensional systems can be classified as accidental or essential. The former can be further distinguished into type-I and…
Two-dimensional Spin-Orbit Dirac Point in Monolayer HfGeTe
Shan Guan, Ying Liu, Zhi-Ming Yu +3
Dirac points in two-dimensional (2D) materials have been a fascinating subject of research, with graphene as the most prominent example. However, the Dirac points in existing 2D ma…
Type-II nodal loops: theory and material realization
Si Li, Zhi-Ming Yu, Ying Liu +5
Nodal loop appears when two bands, typically one electron-like and one hole-like, are crossing each other linearly along a one-dimensional manifold in the reciprocal space. Here we…
Blue Phosphorene Oxide: Strain-tunable Quantum Phase Transitions and Novel 2D Emergent Fermions
Liyan Zhu, Shan-Shan Wang, Shan Guan +4
Tunable quantum phase transitions and novel emergent fermions in solid state materials are fascinating subjects of research. Here, we propose a new stable two-dimensional (2D) mate…
Strain-induced Isostructural and Magnetic Phase Transitions in Monolayer MoN
Yao Wang, Shan-Shan Wang, Yunhao Lu +2
The change of bonding status, typically occurring only in chemical processes, could dramatically alter the material properties. Here, we show that a tunable breaking and forming of…
