Multichannel Phonon Interconversion Drives 90 Polarization Rotation for Stable Domain Walls in Hafnium Oxide
Fatoye Sawyerr, Hamoon Fahrvandi, Pawan Kumar +11
Polarization rotation is a fundamental mechanism in ferroelectric materials, yet how such rotation arises microscopically in fluorite ferroelectrics and gives rise to distinct doma…

Sliding and superlubric moiré twisting ferroelectric transition in HfO2
Jie Sun, Yiheng Shen, Tengfei Cao +1
Despite progress in HfO2 thin-film ferroelectrics, issues like high coercive fields persist, and the dynamics of twisted ferroelectricity remain largely unexplored. Here, we explor…
