Open Access
The origins of high piezoelectric properties in the lead-free (K,Na)NbO3-based tetragonal composition (K0.44Na0.52Li0.04)(Nb0.86Ta0.10Sb0.04)O3 (KNL-NTS) is investigated by quantifying the intrinsic and extrinsic contributions ...
Extrinsic response enhancement at the polymorphic phase boundary in piezoelectric materials

Ochoa Guerrero, Diego A.; Esteves, Giovanni; Jones, Jacob L.; Rubio-Marcos, Fernando; Fernández Lozano, José Francisco; García García, José Eduardo (2016-04-04)
Article
Open Access
Polymorphic phase boundaries (PPBs) in piezoelectric materials have attracted significant interest in recent years, in particular because of the unique properties that can be found in their vicinity. However, to fully ...

Low temperature dielectric relaxation in ordinary perovskite ferroelectrics: enlightenment from high-energy x-ray diffraction

Ochoa Guerrero, Diego A.; Levit Valenzuela, Rafael; Fancher, Christopher M.; Esteves, Giovanni; Jones, Jacob L.; García García, José Eduardo (2017-04-26)
Article
Open Access
Ordinary ferroelectrics exhibit a second order phase transition that is characterized by a sharp peak in the dielectric permittivity at a frequency-independent temperature. Furthermore, these materials show a low temperature ...
