Hybridization-controlled re-entrant electronic phase switching and moire-confined states in twisted bilayer PtTe2
Seoung-Hun Kang, Jeonghwan Ahn, Young-Kyun Kwon
The study uses first‑principles calculations with spin‑orbit coupling to show that twisting a PtTe₂ bilayer causes a non‑monotonic, re‑entrant transition between gapless and gapped…
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…
