Ferroelectricity in van der Waals multilayers via interfacial polarization engineering

npj 2D Materials and Applications
We report a general mechanism for building ferroelectricity in prevailing van der Waals (vdW) multilayers via interfacial engineering. Using sandwiched graphene/boron nitride (BN)/graphene multilayers as an exemplary system, we show that considerable ...

Interfacial Polarization Phenomena in Compressed Nanowires of SbSI

Materials, 2022
The systematic studies of the extrinsic Maxwell–Wagner–Sillars polarization process in compressed antimony sulfoiodide (SbSI) nanowires are carried out by dielectric spectroscopy. The dielectric response is studied in temperature (100≤T≤350) K and frequency (10−3≤f≤106) Hz ranges.

Polarization Saturation in Multilayered Interfacial Ferroelectrics

Advanced Materials
AbstractVan der Waals polytypes of broken inversion and mirror symmetries  have been recently shown to exhibit switchable electric polarization even at the ultimate two‐layer thin limit. Their out‐of‐plane polarization has been found to accumulate in a ladder‐like fashion with each successive layer, offering 2D building blocks for the bottom‐up ...
