Theoretical investigation of the vertical dielectric screening dependence on defects for few-layered van der Waals materials
Amit Singh, Seunghan Lee, Hyeonhu Bae +3
First-principle calculations were employed to analyze the effects induced by vacancies of molybdenum (Mo) and sulfur (S) on the dielectric properties of few-layered MoS2. We explor…
Field-linear anomalous Hall effect and Berry curvature induced by spin chirality in the kagome antiferromagnet Mn3Sn
Xiaokang Li, Jahyun Koo, Zengwei Zhu +2
During the past two decades, it has been established that a non-trivial electron wave-function topology generates an anomalous Hall effect (AHE), which shows itself as a Hall condu…
Exchange-biased topological transverse thermoelectric effects in a Kagome ferrimagnet
Heda Zhang, Jahyun Koo, Chunqiang Xu +3
Kagome metal TbMn6Sn6 was recently discovered to be a ferrimagnetic topological Dirac material by scanning tunneling microscopy/spectroscopy measurements. Here, we report the obser…
Spin and charge interconversion in Dirac semimetal thin films
Wilson Yanez, Yongxi Ou, Run Xiao +17
We report spin-to-charge and charge-to-spin conversion at room temperature in heterostructure devices that interface an archetypal Dirac semimetal, Cd3As2, with a metallic ferromag…
Giant room temperature anomalous Hall effect and magnetically tuned topology in the ferromagnetic Weyl semimetal Co2MnAl
Peigang Li, Jahyun Koo, Wei Ning +9
Weyl semimetals (WSM) have been extensively studied due to their exotic properties such as topological surface states and anomalous transport phenomena. Their band structure topolo…
Intrinsic anomalous Nernst effect amplified by disorder in a half-metallic semimetal
Linchao Ding, Jahyun Koo, Liangcai Xu +9
Intrinsic anomalous Nernst effect (ANE), like its Hall counterpart, is generated by Berry curvature of electrons in solids. Little is known about its response to disorder. In contr…
Density-Functional Theory and Tight-Binding Studies of the Geometry of Hydrogen Adsorbed on Graphynes
Hunpyo Lee, Jahyun Koo, Massimo Capone +2
Using density-functional theory and a tight-binding approach we investigate the physical origin of distinct favourable geometries of adsorbed hydrogen atoms in various graphyne str…
Cohesion Energetics of Carbon Allotropes : Quantum Monte Carlo Study
Hyeondeok Shin, Sinabro Kang, Jahyun Koo +3
We have performed quantum Monte Carlo calculations to study the cohesion energetics of carbon allotropes, including -bonded diamond, -bonded graphene, - hybri…
