Ferroelectricity in CMOS-compatible hafnia (HfO2) is crucial for the fabrication of high-integration nonvolatile memory devices. However, the capture of ferroelectricity in HfO2 requires the stabilization of thermodynamically metastable orthorhombic or rhombohedral phases, which entails the introduc…
