DOI: 10.1002/adma.201601288
Abstract: Sr3 Sn2 O7 is the first room-temperature ferroelectric Sn insulator with switchable electric polarization. The ferroelastic twin domains are observed using a polarized optical microscope. The polarization hysteresis loop clearly demonstrates the ferroelectric property. Intriguing… read more here.

DOI: 10.1126/sciadv.aax5080
Abstract: WTe2, a layered crystalline material, displays both ferroelectricity and metallicity. Coexistence of reversible polar distortions and metallicity leading to a ferroelectric metal, first suggested by Anderson and Blount in 1965, has so far remained elusive.… read more here.

DOI: 10.3390/mi13060887
Abstract: Currently, there is a lack of nonvolatile memory (NVM) technology that can operate continuously at temperatures > 200 °C. While ferroelectric NVM has previously demonstrated long polarization retention and >1013 read/write cycles at room temperature,… read more here.
