Atypical sliding and Moire ferroelectricity in pure multilayer graphene
Liu Yang, Shiping Ding, Jinhua Gao +1
Most non-ferroelectric two-dimensional materials can be endowed with so-called sliding ferroelectricity via non-equivalent homo-bilayer stacking, which is not applicable to mono-el…
Across-Layer Sliding Ferroelectricity in Graphene-Based Heterolayers: Asymmetry of Next Neighbor Interlayer Couplings
Liu Yang, Menghao Wu
Although most two-dimensional (2D) materials are non-ferroelectric with highly symmetric lattices, symmetry breaking may take place in their bilayers upon certain stacking order, g…
Bulk and Two-dimensional Silver and Copper Monohalides: A Unique Class of Materials with Modest Ionicity/Covalency and Ferroelasticity/Multiferroicity
Yaxin Gao, Menghao Wu, Xiao Cheng Zeng
Silver and copper monohalides can be viewed as a class of compounds in the neutral zone between predominantly covalent and ionic compounds, thereby exhibiting neither strong ionici…
Type-II multiferroic HfVCF MXene monolayer with high transition temperature
Jun-Jie Zhang, Linfang Lin, Yang Zhang +3
Achieving multiferroic two-dimensional (2D) materials should enable numerous functionalities in nanoscale devices. Until now, however, predicted 2D multiferroics are very few and w…
Unusual Ferroelectricity of Trans-Unitcell Ion-Displacement and Multiferroic Soliton in Sodium and Potassium Hydroxides
Yangyang Ren, Shuai Dong, Menghao Wu
We show the first-principles evidence of a hitherto unreported type of ferroelectricity with ultra-long ion-displacement in sodium and potassium hydroxides. Even a small amount of…
Proton-transfer Ferroelectricity / Multiferroicity in Rutile Oxyhydroxides
Menghao Wu, Tianci Duan, Chengliang Lu +3
Oxyhydroxide minerals like FeOOH have been a research focus in geology for studying the Earth interior, and also in chemistry for studying oxygen electrocatalysis activity. In this…
Conetronics in 2D Metal-Organic Frameworks: Double Dirac Cones, Magnetic Half Dirac Cones and Quantum Anomalous Hall Effect
Menghao Wu, Zhijun Wang, Junwei Liu +8
Based on recently synthesized Ni3C12S12 class 2D metal-organic frameworks, we predict electronic properties of M3C12S12 and M3C12O12, where M is Zn, Cd, Hg, Be, or Mg with no M orb…
Monolayer MXenes: promising half-metals and spin gapless semiconductors
Guoying Gao, Guangqian Ding, Jie Li +3
Half-metals and spin gapless semiconductors are promising candidates for spintronic applications due to the complete (100%) spin polarization of electrons around the Fermi level. B…
Interference Evidence for Rashba-Type Spin-Split on Semimetallic WTe2 Surface
Qing Li, Jiaqiang Yan, Biao Yang +11
Semimetallic tungsten ditelluride (WTe2) displays an extremely large non-saturating magnetoresistance (XMR), which is the subject of intense interest. This phenomenon is thought to…
