Phonon modes and Raman signatures of MnBi2nTe3n+1 (n=1,2,3,4) magnetic topological heterostructures
Yujin Cho, Jin Ho Kang, Liangbo Liang +8
An intrinsic antiferromagnetic topological insulator can be realized by intercalating Mn-Te bilayer chain in a topological insulator, . $\m…
Polytypism in Few-Layer Gallium Selenide
Soo Yeon Lim, Jae-Ung Lee, Jung Hwa Kim +6
Gallium selenide (GaSe) is one of layered group-III metal monochalcogenides, which has an indirect bandgap in monolayer and direct bandgap in bulk unlike other conventional transit…
Interlayer magnetism in Fe3-xGeTe2
Xiangru Kong, Giang D. Nguyen, Jinhwan Lee +7
FeGeTe is a layered van der Waals magnetic material with a relatively high ordering temperature and large anisotropy. While most studies have concluded the interlayer o…
New Nanoporous Graphyne Monolayer as Nodal Line Semimetal: Double Dirac Points with an Ultrahigh Fermi Velocity
Linyang Li, Xiangru Kong, François M. Peeters
Two-dimensional (2D) carbon materials play an important role in nanomaterials. We propose a new carbon monolayer, named hexagonal-4,4,4-graphyne (H4,4,4-graphyne), which is a nanop…
Quantum anomalous Hall effect in stable 1T-YN monolayer with a large nontrivial band gap and high Chern number
Xiangru Kong, Linyang Li, Ortwin Leenaerts +3
The quantum anomalous Hall (QAH) effect is a topologically nontrivial phase, characterized by a non-zero Chern number defined in the bulk and chiral edge states in the boundary. Us…
New Group V Elemental Bilayers: A Tunable Structure Model with 4,6,8-atom Rings
Xiangru Kong, Linyang Li, Ortwin Leenaerts +2
Two-dimensional (2D) group V elemental materials have attracted widespread attention due to their nonzero band gap while displaying high electron mobility. Using first-principles c…
Carbon-Rich Carbon Nitride Monolayers with Dirac Cones: Dumbbell C4N
Linyang Li, Xiangru Kong, Ortwin Leenaerts +3
Two-dimensional (2D) carbon nitride materials play an important role in energy-harvesting, energy-storage and environmental applications. Recently, a new carbon nitride, 2D polyani…
Gallium Bismuth Halides GaBi-X2 (X= I, Br, Cl) Monolayers with Distorted Hexagonal Framework: Novel Room-Temperature Quantum Spin Hall Insulators
Linyang Li, Ortwin Leenaerts, Xiangru Kong +3
Quantum Spin Hall (QSH) insulators with a large topologically nontrivial bulk gap are crucial for future applications of the QSH effect. Among these, group III-V monolayers and the…
