Emergent Chiral Spin Crystal Phase in (111) SrRuO3 Thin Films
Zhaoqing Ding, Yongjie Xie, Xuejiao Chen +13
Perovskite ruthenates are fascinating playgrounds for exploring topological spin textures, but generally rely on extrinsic mechanisms to trigger the noncoplanar states. Here we rep…

Optical Excitations of Flat Bands Induced by Exciton Condensation in TaPdTe
Shaohui Yi, Zhiyu Liao, Chenhao Liang +10
We report on the charge dynamics of TaPdTe using temperature-dependent optical spectroscopy with polarized light. We observe a metal-insulator transition characterized…

Ferroelectricity in undoped HfO2 down to one-unit-cell on Si substrate
Tiantian Wang, He Zhang, Yongjie Xie +12
Hafnium oxide (HfO2), particularly at low-dimensional scales, exhibits extensive promising applications in ultrahigh density devices like low-power logic and non-volatile memory de…
