Abstract Precipitation hardening has been recently validated as a new mechanism for domain wall pinning and mechanical loss reduction in piezoelectrics. While anisometric precipitates have high pinning strengths, there is limited knowledge about the

Antiferroelectrics are important in emerging energy-storage technologies. Here, the authors present an approach to adjust their local structure and defect chemistry, in order to overcome the current limitations and make them suitable for environmenta

Dislocations are often perceived as a culprit for degradation in functionality. Here, the authors introduce a general framework for engineering dislocations and domain walls and demonstrate its full potential on a ferroelectric BaTiO3 single crystal.

Abstract Lead-free piezoceramics based on the (Ba, Ca)(Zr, Ti)O3 (BCZT) system exhibit excellent electromechanical properties for low-temperature actuation applications, but suffer from relatively high processing temperatures. Here we demonstrate an

Despite the challenges of practical implementation, electrocaloric (EC) cooling remains a promising technology because of its good scalability and high efficiency. Here, we investigate the feasibility of an EC cooling device that couples the EC and e

Dislocations in oxides can be described as charged line defects and means for one-dimensional doping, which can tune electrical and thermal properties. Furthermore, theoretically it was shown that dislocations can pin ferroelectric domain walls. Broa
