Antiferroelectriclike hysteresis loops in PbTiO3/BiFeO3/PbTiO3 sandwich structural film

Solid State Communications, 2008
Abstract PbTiO3/BiFeO3/PbTiO3 sandwich structure has been deposited on Pt/Ti/SiO2/Si substrate by sol-gel method annealing at 600 ∘C. X-ray diffraction analysis revealed that the film was fully crystallized with no impure phase. Antiferroelectriclike hysteresis loop was observed at room temperature under low applied field. Under high applied electric

Giant piezoelectricity of Sm-doped Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals

Science, 2019
Samarium supersensors Piezoelectric materials produce electric charge in response to changes in stress and are thus good sensor materials. One challenge has been growing single-crystal piezoelectrics with uniform properties.

Absence of a PbTiO3 phase transition in PbTiO3/BaTiO3 superlattices

Journal of the European Ceramic Society, 2001
Abstract We have performed X-ray diffraction and Raman spectroscopy on three PbTiO 3 /BaTiO 3 superlattices (PTO/BTO) from room temperature (RT) to 600°C. The superlattices were 4000 A thick and the modulation wavelengths Λ, with equally thick layers of PTO and BTO, were 136, 187 and 357 A.
