Computational symmetry hierarchy of time-reversal-even and -odd spin Hall conductivity tensors in altermagnets
Dameul Jeong, Seoung-Hun Kang, Young-Kyun Kwon
Predicting the full spin Hall conductivity tensor of a magnetic crystal is difficult because crystallographic and magnetic symmetries do not constrain all parts of the response in…
Hybridization-controlled re-entrant electronic phase switching and moire-confined states in twisted bilayer PtTe2
Seoung-Hun Kang, Jeonghwan Ahn, Young-Kyun Kwon
Twisting a van der Waals bilayer changes not only the moiré periodicity but also the local stacking and interlayer hybridization. Here, we show, using fully relaxed first-principle…
Band Renormalization in Monolayer MoS2 Induced by Multipole Screening
Woojoo Lee, Seungwoo Yoo, Marios Zacharias +2
Dielectric screening plays a crucial role in shaping the electronic structure of two-dimensional (2D) materials. In 2D semiconductors, screened Coulomb interactions arising from th…
Optimizing Density Functional Theory for Strain-Dependent Magnetic Properties of Monolayer MnBiTe with Diffusion Monte Carlo
Jeonghwan Ahn, Swarnava Ghosh, Seoung-Hun Kang +6
Monolayer MnBiTe (MBT) is an intrinsically magnetic topological insulator whose magnetic response is strongly affected by strain and electron correlation. In density fu…
Overcoming Quantum Resistivity Scaling in Nanoscale Interconnects Using Delafossite PdCoO2
Seoung-Hun Kang, Youngjun Lee, Sangmoon Yoon +4
Continued scaling into the sub 7 nm regime exacerbates quantum limited resistivity in Cu interconnects. We evaluated layered PdCoO2 and explicitly benchmarked it against Cu to iden…
Momentum-Resolved Relaxation-Time Approach for Size-Dependent Conductivity in Anisotropic Metallic Films
YoungJun Lee, Jin Soo Lee, Seungjun Lee +2
Shrinking CMOS interconnect dimensions to the nanometer scale intensifies electron scattering at surfaces, interfaces, and grain boundaries, causing severe conductivity loss and ch…
Magnetic and Crystal Symmetry Effects on Spin Hall Conductivity in Altermagnets
Dameul Jeong, Seoung-Hun Kang, Young-Kyun Kwon
Altermagnets, which reconcile zero net magnetization with pronounced spin splitting, offer fresh opportunities for spin-based functionalities in next-generation electronic and spin…
Reversible Modification of Rashba States in Topological Insulators at Room Temperature by Edge Functionalization
Wonhee Ko, Seoung-Hun Kang, Qiangsheng Lu +7
Quantum materials with novel spin textures from strong spin-orbit coupling (SOC) are essential components for a wide array of proposed spintronic devices. Topological insulators ha…
