Ferroelectric random access memory (FeRAM) plays a vital role in information storage due to its unique advantages, driving the demand for high-capacity and high-density solutions. In this paper, a series of PbZr1-xTixO3 (x = 6 %, 8 %, 10 %, 12 %, 14 %) films were prepared using sol-gel and spin-coating methods. As the Ti content increases, the enhancement effect of the ferroelectric order is reflected structurally in XRD and Raman spectra, and electrically in the dielectric and ferroelectric properties. Notably, for x = 12 %, the P-E hysteresis loop exhibits slightly pinched and double-like, and the peaks of the I-V curve are split on both the positive and negative field sides. This ferroelectric behavior is caused by an underlying triple-well free-energy landscape, which is the basis of tristate ferroelectric memory. The measurement results show that the "±1" and "0" states of PbZr0.88Ti0.12O3 film under electric field cycling exhibit excellent programmability. It also achieves promising data retention up to 1000s and endurance up to 107 cycles. This investigation not only verifies the feasibility of applying tristate ferroelectric memory to PZT-based films but also provides a facile method for fabricating tristate ferroelectric memory devices. © 2025 Elsevier Ltd and Techna Group S.r.l.

Flexible piezoelectric materials capable of withstanding large deformation play key roles in flexible electronics. Ferroelectric ceramics with a high piezoelectric coefficient are inherently brittle, whereas polar polymers exhibit a low piezoelectric coefficient. Here we report a highly stretchable/compressible piezoelectric composite composed of ferroelectric ceramic skeleton, elastomer matrix and relaxor ferroelectric-based hybrid at the ceramic/matrix interface as dielectric transition layers, exhibiting a giant piezoelectric coefficient of 250 picometers per volt, high electromechanical coupling factor keff of 65%,ultralow acoustic impedance of 3MRyl and high cyclic stability under 50% compression strain. The superior flexibility and piezoelectric properties are attributed to the electric polarization and mechanical load transfer paths formed by the ceramic skeleton, and dielectric mismatch mitigation between ceramic fillers and elastomer matrix by the dielectric transition layer. The synergistic fusion of ultrahigh piezoelectric properties and superior flexibility in these polymer composites is expected to drive emerging applications in flexible smart electronics.
