Metal-insulator phase separation in KTaO3-based two-dimensional electron gas
Jinlei Zhang, Jiayong Zhang, Dapeng Cui +8
Electronic phase separation (EPS) originates from an incomplete transformation between electronic phases, causing the inhomogeneous spatial distribution of electronic properties. I…
Observation of room-temperature ferroelectricity in elemental Te nanowires
Jinlei Zhang, Jiayong Zhang, Yaping Qi +10
Ferroelectrics are essential in low-dimensional memory devices for multi-bit storage and high-density integration. A polar structure is a necessary premise for ferroelectricity, ma…
Dynamic crystallography reveals spontaneous anisotropy in cubic GeTe
Simon A. J. Kimber, Jiayong Zhang, Charles H. Liang +10
Cubic energy materials such as thermoelectrics or hybrid perovskite materials are often understood to be highly disordered. In GeTe and related IV-VI compounds, this is thought to…
Study of anharmonicity in Zirconium Hydrides using inelastic neutron scattering and ab-initio computer modeling
Jiayong Zhang, Yongqiang Cheng, Alexander I. Kolesnikov +3
The anharmonic phenomena in Zirconium Hydrides and Deuterides, including ε-ZrH2, γ-ZrH, and γ-ZrD, have been investigated from aspects of inelastic neutron scattering (INS) and lat…
Novel Chern insulators with half-metallic edge states
Yang Xue, Bao Zhao, Yan Zhu +5
The central target of spintronics research is to achieve flexible control of highly efficient and spin-polarized electronic currents. Based on first-principles calculations and k-p…
Origin of topologically trivial states and topological phase transitions in low-buckled plumbene
Yue Li, Jiayong Zhang, Bao Zhao +2
Combining tight-binding (TB) models with first-principles calculations, we investigate electronic and topological properties of plumbene. Different from the other two-dimensional (…
Giant Spin-valley Polarization and Multiple Hall Effect in Functionalized Bi Monolayers
Tong Zhou, Jiayong Zhang, Hua Jiang +2
Valleytronic materials, characterized by local extrema (valley) in their bands, and topological insulators have separately attracted great interest recently. However, the interplay…
Strong magnetization and Chern insulators in compressed graphene/CrI van der Waals heterostructures
Jiayong Zhang, Bao Zhao, Tong Zhou +3
Graphene-based heterostructures are a promising material system for designing the topologically nontrivial Chern insulating devices. Recently, a two-dimensional (2D) monolayer ferr…
Coupling effect of topological states and Chern insulators in two-dimensional triangular lattices
Jiayong Zhang, Bao Zhao, Yang Xue +2
We investigate topological states of two-dimensional (2D) triangular lattices with multi-orbitals. Tight-binding model calculations of a 2D triangular lattice based on $\emph{p}_{x…
Chern insulators without band inversion in MoS2 monolayers with 3d adatoms
Xinyuan Wei, Bao Zhao, Jiayong Zhang +3
Electronic and topological properties of MoS2 monolayers endowed with 3d transition metal (TM) adatoms (V-Fe) are explored by using ab initio methods and k.p models. Without the co…
Quantum Spin-quantum Anomalous Hall Effect with Tunable Edge States in Sb Monolayer-based Heterostructures
Tong Zhou, Jiayong Zhang, Yang Xue +4
A novel topological insulator with tunable edge states, called quantum spin-quantum anomalous Hall (QSQAH) insulator, is predicted in a heterostructure of a hydrogenated Sb (SbH) m…
