Piezoelectricidad y ferroelectricidad en biomateriales
(2011-12)
The present article is a review of the concepts of ferroelectric and piezoelectric materials, as well as the application in
complex compounds such as inorganic-organic hybrids using atomic force microscopy (AFM) and ...
Nature of defects for bismuth layered thin films grown on Pt electrodes
(American Institute of Physics (AIP), 2007-02-19)
The authors investigated the influence of defects on the piezoelectric and dielectric properties of Bi4Ti3O12 (BIT), SrBi4Ti4O15 (SBTi) and CaBi4Ti4O15 (CBTi144) thin films by x-ray photoemission spectroscopy measurements. ...
Electromechanical properties of calcium bismuth titanate films: A potential candidate for lead-free thin-film piezoelectrics
(American Institute of Physics (AIP), 2006-02-13)
CaBi4Ti4O15 (CBTi144) thin films were evaluated for use as lead-free thin-film piezoelectrics in microelectromechanical systems. The films were grown by the polymeric precursor method on (100)Pt/Ti/SiO2/Si substrates. The ...
Piezoelectric properties of Bi4Ti3O12 thin films annealed in different atmospheres
(Elsevier B.V., 2007-05-03)
Bismuth titanate (Bi4Ti3O12-BIT) films were evaluated for use as lead-free piezoelectric thin-films in micro-electromechanical systems. The films were grown by the polymeric precursor method on Pt/Ti/SiO2/Si (1 0 0) (Pt) ...

A study approach on ferroelectric domains in BaTiO3
(2016-10-01)
Atomic Force Acoustic Microscopy (AFAM) and Piezoresponse Force Microscopy (PFM) were used to study local elastic and electromechanical response in BaTiO3 ceramics. A commercial multi-mode Scanning Probe Microscopy (SPM) ...
Imprint behavior and polarization relaxation of PLZT thin films
(Taylor & Francis Ltd, 2018-01-01)
Thickness dependence of imprint and polarization dynamics of Pb1-xLax(Zr1-yTiy)(1-x/4)O-3 (PLZT) thin films is reported in this work. Asymmetries in the histograms of the local piezoresponse reveal an imprint effect in the ...
Physical properties and reentrant behavior in PLZT thin films
(Taylor & Francis Ltd, 2017-01-01)
La-modified lead zirconate titanate (PLZT) thin films were prepared to study their physical properties at macro- and nanoscale. Piezoresponse force microscopy (PFM) studies suggest a local imprint behavior at room temperature. ...
