Higher-order Topological Phases of Magnons in van der Waals Honeycomb Ferromagnets
Yun-Mei Li, Ya-Jie Wu, Xi-Wang Luo +2
We theoretically propose a second-order topological magnon insulator by stacking the van der Waals honeycomb ferromagnets with antiferromagnetic interlayer coupling. The system exh…
Colloquium: Physical properties of group-IV monochalcogenide monolayers
Salvador Barraza-Lopez, Benjamin M. Fregoso, John W. Villanova +2
We survey the state-of-the-art knowledge of ferroelectric and ferroelastic group-IV monochalcogenide monolayers. These semiconductors feature remarkable structural and mechanical p…
Intrinsic 2D-XY ferromagnetism in a van der Waals monolayer
Amilcar Bedoya-Pinto, Jing-Rong Ji, Avanindra Pandeya +6
Long before the recent fascination with two-dimensional materials, the critical behaviour and universality scaling of phase transitions in low-dimensional systems has been a topic…
Direct observation of handedness-dependent quasiparticle interference in the two enantiomers of topological chiral semimetal PdGa
Paolo Sessi, Feng-Ren Fan, Felix Küster +16
It has recently been proposed that combining chirality with topological band theory may result in a totally new class of fermions. These particles have distinct properties: they ap…
Towards Weyltronics: Realization of epitaxial NbP and TaP Weyl Semimetal thin films
Amilcar Bedoya-Pinto, Avanindra Kumar Pandeya, Defa Liu +7
Weyl Semimetals (WSMs), a recently discovered topological state of matter, exhibit an electronic structure governed by linear band dispersions and degeneracy (Weyl) points leading…
Coexistence of New Fermions in Topological Semimetal TaS
Jian-Peng Sun, Dong Zhang, Kai Chang
We theoretically propose that, the single crystal formed TaS is a new type of topological semimetal, hosting ring-shaped gapless nodal lines and triply degenerate points (TDPs) in…
Towards Fast Multicolor Photodetectors based on Graphene Contacted Vertical p-GaSe/n-InSe van der Waals Heterostructure
Faguang Yan, Dong Zhang, Wengang Luo +6
We investigated the electronic and optoelectronic properties of vertical van der Waals heterostructure photodetectors using layered p type GaSe and n type InSe, with graphene as th…
Half metallic and insulating phases in BN/Graphene lateral heterostructures
Dong Zhang, Maosheng Miao, Fuhua Yang +2
We investigate theoretically the electronic structure of graphene and boron nitride (BN) lateral heterostructures, which were fabricated in recent experiments. The first-principles…
