Measurement of effective piezoelectric coefficients of PZT thin films for energy harvesting application with interdigitated electrodes
Paul Muralt, Andrea Mazzalai, Nachiappan Chidambaram
Interdigitated electrode (IDE) systems with lead zirconate titanate (PZT) thin films play an increasingly important role for two reasons: first, such a configuration generates higher voltages than parallel plate capacitor-type electrode (PPE) structures, a ...
Institute of Electrical and Electronics Engineers2012Substrate Clamping Effects on Irreversible Domain Wall Dynamics in Lead Zirconate Titanate Thin Films
The role of long-range strain interactions on domain wall dynamics is explored through macroscopic and local measurements of nonlinear behavior in mechanically clamped and released polycrystalline lead zirconate-titanate (PZT) films. Released films show a ...

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Evgeny Mikheev
Polarization reversal in ferroelectric nanomesas of polyvinylidene fluoride with trifluoroethylene has been probed by ultrahigh vacuum piezoresponse force microscopy in a wide temperature range from 89 to 326 K. In dramatic contrast to the macroscopic data ...
American Physical Society2012Evolving morphotropic phase boundary in lead-free (Bi[sub 1/2]Na[sub 1/2])TiO[sub 3]–BaTiO[sub 3] piezoceramics
The correlation between structure and electrical properties of lead-free (1-x)(Bi1/2Na1/2)TiO3-xBaTiO(3) (BNT-100xBT) polycrystalline piezoceramics was investigated systematically by in situ synchrotron diffraction technique, combined with electrical prope ...
American Institute of Physics2011Large Electric-Field Induced Strain in BiFeO3 Ceramics
Dragan Damjanovic, Marija Kosec
Large bipolar strain of up to 0.36% (peak-to-peak value) was measured in BiFeO3 ceramics at low frequency (0.1 Hz) and large amplitude (140 kV/cm) of the driving field. This strain is comparable to that achievable in highly efficient morphotropic phase bou ...

2011Polarization Reversal in BiFeO3 Capacitors: Complex Behavior Revealed by PFM
Nava Setter, Paul Muralt, Alexander Tagantsev, Igor Stolichnov, Enrico Colla, Monika Iwanowska
Polarization reversal in BiFeO3 (BFO) thin films in a parallel-plate capacitor configuration has been explored using piezo-force microscopy (PFM). Through-electrode mapping of the local piezoresponse allows for direct observation of the domain growth, whic ...

The development of wireless and mobile communication in the last decade led to the elaboration of new components based on thin films with continually increasing performance and reduced fabrication cost. A fundamental element for mobile communication is the ...
EPFL2010What Can Be Expected From Lead-Free Piezoelectric Materials?
Dragan Damjanovic, Li Jin, Naama Klein, Viktor Porokhonskyy
The reasons for the lower piezoelectric properties in the most studied lead-free piezoelectrics, modified (K,Na)NbO3 and (Bi0.5Na0.5)TiO3, are discussed. Contributions from domain wall motion and properties at the morphotropic phase boundary are considered ...
2010First-principles study of high-field piezoelectricity in tetragonal PbTiO3
Anindya Roy, Massimiliano Stengel
We calculate from first principles the nonlinear piezoelectric response of ferroelectric PbTiO3 for the case of a polarization-enhancing electric field applied along the tetragonal axis. We focus mainly on the case of fixed in-plane lattice constants, corr ...
