Unified understanding to the rich electronic-structure evolutions of 2D black phosphorus under pressure
Yu-Meng Gao, Yue-Jiao Zhang, Xiao-Lin Zhao +9
The electronic structure evolutions of few-layer black phosphorus (BP) under pressure shows a wealth of phenomena, such as the nonmonotonic change of direct gap at the Γ point, the…
Elemental topological ferroelectrics and polar metals of few-layer materials
Hu Zhang, Lulu Zhao, RuiFeng Zhang +6
Ferroelectricity can exist in elemental phases as a result of charge transfers between atoms occupying inequivalent Wyckoff positions. We investigate the emergence of ferroelectric…
Momentum matching and band-alignment type in van der Waals heterostructures: Interfacial effects and materials screening
Yue-Jiao Zhang, Yin-Ti Ren, Xiao-Huan Lv +10
Momentum-matched type II van der Waals heterostructures (vdWHs) have been designed by assembling layered two-dimensional semiconductors (2DSs) with special band-structure combinati…
Parity-breaking in single-element phases: Ferroelectric-like elemental polar metals
Hu Zhang, Bei Deng, Wei-Chao Wang +1
Polar metals based on binary and ternary compounds have been demonstrated in literature. Here, we propose a design principle for ferroelectric-like elemental polar metals and relat…
Interlayer Quasi-Bonding Interactions in 2D Layered Materials: A Classification According to the Occupancy of Involved Energy Bands
Yuan-Tao Chen, Peng-Lai Gong, Yin-Ti Ren +5
Recent studies have revealed that the interlayer interaction in two-dimensional (2D) layered materials is not simply of van der Waals character but could coexist with quasi-bonding…
Hole- and electron-injection driven phase transitions in transition metal dichalcogenides and beyond: A unified understanding
Xiao-Huan Lv, Meng-Qi Wu, Yin-Ti Ren +7
The phase transitions among polymorphic two-dimensional (2D) transition metal dichalcogenides (TMDs) have attracted increasing attention for their potential in enabling distinct fu…
Influences of spin-orbit coupling on Fermi surfaces and Dirac cones in ferroelectric-like polar metals
Hu Zhang, Wei Huang, Jia-Wei Mei +1
Based on first-principles calculations and k .p effective models, we report physical properties of ferroelectric-like hexagonal polar metals with P63mc symmetry, which are distinct…
