Anisotropic Schottky-barrier-height in high-symmetry 2D WSe: Momentum-space anisotropy
Nuo Xu, Xiao-Lin Zhao, Meng-Xue Ren +5
It is usually supposed that only low-symmetry two-dimensional (2D) materials exhibit anisotropy, here we show that high-symmetry 2D semiconductors can show significant anisotropy i…
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…
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…
Ferroelectricity and Rashba effect in GeTe
C. Rinaldi, D. Di Sante, A. Giussani +9
GeTe has been proposed as the father compound of a new class of functional materials displaying bulk Rashba effects coupled to ferroelectricity: ferroelectric Rashba semiconductors…
