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…
Thickness-Dependent Polaron Crossover in Tellurene
Kunyan Zhang, Chuliang Fu, Shelly Kelly +12
Polarons, quasiparticles arising from electron-phonon coupling, are crucial in understanding material properties such as high-temperature superconductivity and colossal magnetoresi…
Optimizing Density Functional Theory for Strain-Dependent Magnetic Properties of MnBiTe with Diffusion Monte Carlo
Swarnava Ghosh, Jeonghwan Ann, Seoung-Hun Kang +6
In this study, we evaluate the predictive power of density functional theory (DFT) for the magnetic properties of MnBi\(_2\)Te\(_4\) (MBT), an intrinsically magnetic topological in…
