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…
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…
Coexistence of superconductivity and topological band in a van der Waals Sn1-xInxBi2Te4 crystal
Hoyeon Jeon, Saban Hus, Jewook Park +7
The realization of topological surface states and superconductivity within a single material platform is a crucial step toward achieving topologically nontrivial superconductivity.…
