Extensive domain wall contribution to strain in a (K,Na)NbO3-based lead-free piezoceramics quantified from high energy X-ray diffraction
Ochoa Guerrero, Diego A.; Esteves, Giovanni; Iamsasri, Thanakorn; Rubio-Marcos, Fernando; Fernández Lozano, José Francisco; García García, José Eduardo; Jones, Jacob L. (Elsevier, 2016-08)
Article
Accés obertThe 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
Accés obertPolymorphic 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
Accés obertOrdinary 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 ...
