Correlation-driven tunability of altermagnetism in RuO
Ina Park, Dongwook Kim, Inho Lee +3
RuO has been regarded as a prototypical candidate for metallic altermagnet, offering a potential platform for high-speed and high-efficiency spintronics. However, the magnetic…
Layer Edge States Stabilized by Internal Electric Fields in Two-dimensional Hybrid Perovskites
Jisook Hong, David Prendergast, Liang Z. Tan
Two-dimensional (2D) organic-inorganic hybrid perovskites have been intensively explored for recent years, due to their tunable band gaps and exciton binding energies, and increase…
Enhancement of Giant Rashba Splitting in BiTeI under Asymmetric Interlayer Interaction
Taesu Park, Jisook Hong, Ji Hoon Shim
We carry out density functional theory calculation to enhance the Rashba spin splitting (RSS) of BiTeI by modifying the interlayer interaction. It is shown that RSS increases as th…
Experimental observation of hidden Berry curvature in inversion-symmetric bulk 2H-WSe2
Soohyun Cho, Jin-Hong Park, Jisook Hong +11
We investigate the hidden Berry curvature in bulk 2H-WSe2 by utilizing the surface sensitivity of angle resolved photoemission (ARPES). The symmetry in the electronic structure of…
Direct visualization of coexisting channels of interaction in CeSb
Sooyoung Jang, Robert Kealhofer, Caolan John +7
Our understanding of correlated electron systems is vexed by the complexity of their interactions. Heavy fermion compounds are archetypal examples of this physics, leading to exoti…
Giant Rashba-type spin splitting through spin-dependent interatomic-hopping
Jisook Hong, Jun-Won Rhim, Inkyung Song +3
We have performed density functional theory calculation and tight binging analysis in order to investigate the mechanism for the giant Rashba-type spin splitting (RSS) observed in…
Control of Valley Degeneracy in MoS2 by Layer Thickness and Electric Field and Its Effect on Thermoelectric Properties
Jisook Hong, Changhoon Lee, Jin-Seong Park +1
We have investigated the valley degeneracy of MoS2 multilayers and its effect on thermoelectric properties. By modulating the layer thickness and external electric field, the hole…
