Tunable ferroelectricity and anisotropic electric transport in monolayer -GeSe
Shan Guan, Chang Liu, Yunhao Lu +2
Low-dimensional ferroelectricity has attracted tremendous attention due to its huge potential in device applications. Here, based on first-principles calculations, we predict the e…
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…
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…
Tunable Hyperbolic Dispersion and Negative Refraction in Natural Electride Materials
Shan Guan, Shao Ying Huang, Yugui Yao +1
Hyperbolic (or indefinite) materials have attracted significant attention due to their unique capabilities for engineering electromagnetic space and controlling light propagation.…
Tunable Half-metallic Magnetism in Atom-thin Holey Two-dimensional CN Monolayer
Sai Gong, Wenhui Wan, Shan Guan +5
Exploring two-dimensional (2D) materials with magnetic ordering is a focus of current research. It remains a challenge to achieve tunable magnetism in a material of one-atom-thickn…
