Study of vacancy ordering and the boson peak in metastable cubic Ge-Sb-Te using machine learning potentials
Young-Jae Choi, Minjae Ghim, Seung-Hoon Jhi
The mechanism of the vacancy ordering in metastable cubic Ge-Sb-Te (c-GST) that underlies the ultrafast phase-change dynamics and prominent thermoelectric properties remains elusiv…

Robustness of the intrinsic anomalous Hall effect in Fe3GeTe2 to a uniaxial strain
Mijin Lim, Byeonghyeon Choi, Minjae Ghim +2
Fe3GeTe2 (FGT), a ferromagnetic van der Waals topological nodal line semimetal, has recently been studied. Using first-principles calculations and symmetry analysis, we investigate…

Coexistence of spontaneous polarization and superconductivity in hole-doped oxyhydrides ATiO_2H (A=K, Rb, Cs): first-principles study
Minjae Ghim, Nobuya Sato, Ryosuke Akashi +2
The polar metal is a material that hosts both polar distortion and metallicity. Such a material is expected to show exotic magneto-electric phenomena if superconducts. Here, we the…
