Piezoelectric Properties of SrBi4Ti4O15 Ferroelectric Ceramics

Nava Setter, Dragan Damjanovic

The dynamic piezoelectric response of SrBi4Ti4O15 ceramics with Aurivillius structure was investigated at high alternating stress, low frequencies (0.01 to 100 Hz), and temperatures from 20 to 200 degreesC. The piezoelectric nonlinearity, observed only at ...

Extrinsic contributions to the piezoelectric response of lead-based ferroelectrics

The present study aims at a better understanding of the high piezoelectric properties encountered in lead-based ferroelectrics by focusing on the extrinsic contributions to the response. The main characteristics of these materials are the highly nonlinear ...

Preisach modeling of piezoelectric nonlinearity in ferroelectric ceramics

Nava Setter, Dragan Damjanovic

Piezoelectric response nonlinearity is approached using the Preisach description of hysteretic systems as collection of distributed bistable units. The Preisach model and its recent physical interpretation in terms of moving domain wall in a stochastically ...

In-plane piezoelectric coefficient of PZT thin films as a function of composition

Paul Muralt, Stéphane Hiboux, Andreas Seifert, Nicolas Ledermann

The effective piezoelectric coefficient e(31) has been measured on sol-gel processed Pb(ZrxTi1-x)O-3 thin films with Zr concentrations ranging from 45 to 60%. The largest value was observed at 45% Zr, although dielectric constant and effective d(33) peak a ...

Photoinduced poling of lead titanate zirconate thin films

Nava Setter

The influence of ultraviolet (UV) illumination on piezoelectric properties is investigated in lead zirconate titanate (PZT) thin films. It is found that the poling procedure is more effective when the film is exposed to a broadband UV light in the presence ...
