Critical mechanical and electrical transition behavior of BaTiO3: The observation of mechanical double loop behavior

Dragan Damjanovic

Strain response of polycrystalline barium titanate (BaTiO3) was investigated under high unipolar electric field (0 to 4 kV/mm) and compressive stress (0 to 400 MPa) in the temperature range from 25 to 160 degrees C. In the vicinity of the Curie point (T-C) ...

Elastic, dielectric, and piezoelectric anomalies and Raman spectroscopy of 0.5Ba(Ti0.8Zr0.2)O3-0.5(Ba0.7Ca0.3)TiO3

Dragan Damjanovic, Alberto Biancoli, Leili Batooli, Amirhossein Vahabzadeh

The solid solution 0.5Ba(Ti0.8Zr0.2)O-3-0.5(Ba0.7Ca0.3)TiO3 (BCZT) is a promising lead-free piezoelectric material with exceptionally high piezoelectric coefficients. The strong response is related to structural instabilities close to ambient temperature. ...

Structure and the Electrical Properties of Pb(Zr,Ti)O3 - Zirconia Composites

Dragan Damjanovic, Marija Kosec

In this work, the effect of introducing tetragonal yttria-stabilized zirconia (TZ) particles in soft [Pb0.98Ba0.01][(Zr0.53Ti0.47)(0.98)Nb-0.02]O-3 (PZT) was investigated. Both microstructure and electrical properties of the PZT-xTZ (x = 0, 2, 5, 10, 20 vo ...

Stretching cells with DEAs

Herbert Shea, Samuel Rosset, Samin Akbari

Biological cells regulate their biochemical behavior in response to mechanical stress present in their organism. Most of the available cell cultures designed to study the effect of mechanical stimuli on cells are cm2 area, far too large to monitor single c ...

Impact of Strain Effects on the Stability of Ising Walls in Ferroelectrics

Nava Setter, Alexander Tagantsev, Petr Yudin

The stability of Ising 180-degree domain walls with respect to appearance of chirality is analytically studied in tetragonal perovskite-type ferroelectrics taking into account electro-mechanical coupling. It is shown that the widely used approximation negl ...

Microstructure and dielectric properties of piezoelectric magnetron sputtered w-ScxAl1-xN thin films

Paul Muralt, Ramin Matloub Aghdam

Piezoelectric wurtzite ScxAl1-xN (x = 0, 0.1, 0.2, 0.3) thin films were epitaxially grown by reactive magnetron co-sputtering from elemental Sc and Al targets. Al2O3(0001) wafers with TiN(111) seed and electrode layers were used as substrates. X-ray diffra ...
