Influence of calcium concentration on the structural and electrical properties of PZT ceramic
(2015-01-01)
Lead zirconate titanate, with Zr/Ti ratio of 53/47 was prepared by the polymeric precursor method. The powders were doped with 0, 0.2, 0.4 end 0.6 mol% of Ca2+ and characterized by XRD. The percentages of tetragonal and ...
Piezoelectric materials
(2016-01-01)
Piezoelectricity is a phenomenon in which certain crystalline substances develop an electric field when subjected to pressure force, or conversely, exhibit a mechanical deformation when subjected to an electric field. This ...
Electromechanical characterization of piezoelectric polymer thin films in a broad frequency range
(Elsevier, 2014-08)
Piezoelectric materials are usually characterized using resonant methods. However, piezoelectric polymers are used in broadband devices, thus requiring characterization over a wide range of frequencies. In this work, we ...
Impact of oxygen atmosphere on piezoelectric properties of CaBi2Nb2O9 thin films
(Elsevier B.V., 2007-08-01)
CaBi2Nb2O9 (CBNO) thin films were deposited on platinum-coated silicon substrates by the polymeric precursor method, and were annealed in air and in an oxygen atmosphere. The structure, surface morphology and electrical ...
