The stress-assisted enhancement of piezoelectric properties due to mechanically incompatible domain structures in BaTiO3

Nava Setter, Alexander Tagantsev, Dragan Damjanovic, Tomas Sluka, Enrico Colla, Mahamudu Mtebwa

The piezoelectric properties of tetragonal BaTiO3 (BTO) crystals with a high density of 90° twin domain boundaries were experimentally investigated by Wada and Tsurumi (2004 Br. Ceram. Trans. 103 93). These crystals with engineered dense domain structures ...

A morphotropic phase boundary system based on polarization rotation and polarization extension

Dragan Damjanovic

Many ferroelectric solid solutions exhibit enhanced electromechanical properties at the morphotropic boundary separating two phases with different orientations of polarization. The mechanism of properties enhancement is associated with easy paths for polar ...

Comments on origins of enhanced piezoelectric properties in ferroelectrics

Dragan Damjanovic

This review discusses recent advances in understanding origins of large piezoelectric properties in some ferroelectric materials. In particular, it addresses the role of polarization rotation and monoclinic phases. It is suggested that the polarization rot ...

Instrument-independent specification of the diffraction geometry and polarization state of the incident X-ray beam

This work augments the proposal of Schwarzenbach & Flack [J. Appl. Cryst. (1989), 22, 601-605], who have advocated the use of a diffractometer-independent definition of the azimuthal angle

\psi

to specify the diffractiongeometry of a Bragg reflection. It ...

A study of polarization effects in metal-ferroelectric-oxide-semiconductor capacitors

Mihai Adrian Ionescu, Giovanni Antonio Salvatore, Alexandru Rusu

In this paper we report the fabrication and detailed electrical characterization of a Metal-Ferroelectric-Oxide-Semiconductor Capacitor aiming at the extraction of the polarization characteristic. In order to evaluate the electrical performances of the fer ...

Polarization sensitive diffuser

Hans Peter Herzig, Toralf Scharf

With help of liquid crystal polymers (LCP) a polarization sensitive diffuser has been realized. By using convex microstructures made of LCP and an index matching layer, two distinct functions depending on the orientation of the device and the polarization ...

Micro-optical polarizer with high efficiency

Hans Peter Herzig, Toralf Scharf

Based on liquid crystal polymers (LCP) a compact micro-optical polarizer with high efficiency has been designed and realized. By using cylindrical mierolens arrays made of LCP and index matching layer, a complete separation of both polarization components ...

Design and performance of a DNP prepolarizer coupled to a rodent MRI scanner

Rolf Gruetter, Arnaud Comment, Sami Jannin, Jacques Van Der Klink, Fiodar Kurdzesau

For most of the last forty years, the techniques of Dynamic Nuclear Polarization (DNP) have been confined to particle-physics laboratories building polarized targets, but recently it has been shown that samples similar to a solid target can be transformed ...

Phase transitions, anisotropy and domain engineering

Matthew Davis

Relaxor-ferroelectric single crystals PZN-xPT [(1-x)Pb(Zn1/3Nb2/3)O3-xPbTiO3] and PMN-xPT [(1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3] continue to attract much interest due to their anomalously large piezoelectric properties (d33 > 2000 pm/V; k33 > 90%) when poled ("do ...

Development of actuators using PVDF piezoelectric polymer

Jürgen Brugger

Piezoelectricity is the propriety of materials that relates mechanical deformation as a function of applied voltage and vice-versa. The advantage of using these materials as actuators is the fast response and low power consumption when compared with tradit ...
