Defect-Charge-Driven 90° Switching in HfO2
Muting Xie, Hongyu Yu, Zhihao Dai +3
Hafnium dioxide (HfO2) is a CMOS-compatible ferroelectric showing both 180° and 90° switching, yet the microscopic nature of the 90° pathway remains unresolved. We show that the…

Moiré-Induced Magnetoelectricity in Twisted Bilayer NiI2
Haiyan Zhu, Hongyu Yu, Weiqin Zhu +3
Twisted magnetic van der Waals (vdW) materials offer a promising route for multiferroic engineering, yet modeling large-scale moiré superlattices remains challenging. Leveraging a…
