Antiferrodistortive Matrix Engineering Reprograms Polarization Pathways for Ultrahigh Energy Storage at Moderate Electric Fields

ABSTRACT Relaxor ferroelectrics (RFEs) are promising dielectric materials for pulsed multilayer ceramic capacitors because of their rapid polarization response. However, under practical electric fields, polarization rapidly approaches saturation as polar nanoregions exhaust their...

Layer Dependent Ferroelectricity and Electromechanically Coupled Polarization in Two-Dimensional 1T′-ReS2

Abstract Two-dimensional (2D) van der Waals (vdW) materials with sliding ferroelectricity exhibit an enormous potential for next-generation nanodevices. Among these, 1T′-ReS2 with an ultralow symmetry stands out as a pivotal candidate. However, the fundamental scientific mechanis...
