Piezoelectric ceramics with high piezoelectricity and broad temperature usage range
Journal of Materiomics, 2020 There is a general observation that the Curie temperature and piezoelectric property of the ferroelectric ceramics can be enhanced only at the expense of each other, i.e., higher piezoelectricity, lower Curie temperature, thus, limits their applications ...

Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry
Advanced Functional Materials, EarlyView.A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result
