We present a critical review that encompasses the fundamentals and state-of-the-art
knowledge of barium titanate-based piezoelectrics. First, the essential crystallography …

Ferroelectrics have a spontaneous electrical polarization that is arranged into domains and
can be reversed by an externally-applied field. This high versatility makes them useful in …

There has been considerable progress in the development of large strain lead-free
perovskite ferroelectrics over the past decade. Under certain conditions, the …

Piezoelectric materials (PEMs) find a wide spectrum of applications that include, but are not
limited to, sensors, actuators, semiconductors, memory devices, and energy harvesting …

This study evaluates the change of flow stress as related to dislocation density in SrTiO3
single crystals in order to provide guidance for later electrical studies. The key parameters …

The fracture toughness of unpoled and electrically poled lead-free KNN-based piezoelectric
ceramics with the composition of 0.92 KNN-0.02 Bi 0.5 Li 0.5 TiO 3-0.06 BaZrO 3 was …

The nanomechanical properties of polycrystalline “hard” and “soft” lead zirconate titanate
(PZT)(abbreviated as PZT-H and PZT-S, respectively) are measured on samples having …

Here we report the structural, electrical, mechanical, and electromechanical characterization
of pyrochlore-free (1− x) Pb (Mg 1/3 Nb 2/3 O 3)-xPbTiO 3 at x= 0.3 (PMN-0.3 PT), from the …

Lead-free perovskite ferroelectrics are of great interest to the scientific community and are
beginning to replace lead-based ferroelectrics in specific applications. Although many lead …

The fracture toughness in the lead‐free relaxor ferroelectric (1− x)(Na1/2Bi1/2) TiO3–xBaTiO
3 was investigated utilizing the surface crack in flexure method. To allow a comprehensive …
