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 ...

Zipping it up: DEAs independent of the elastomer's electric breakdown field

Herbert Shea, Luc Maffli, Pit Gebbers, Christoph Stamm

We demonstrate here an alternative dielectric elastomer actuator (DEA) structure, which relies on the compliant nature of elastomer membranes but does not require any electric field in the elastomer. Our elastomer zipping device is a macroscopic version of ...

Broadband Dielectric Response in Hard and Soft PZT

Li Jin

Lead zirconate titanate (Pb(Zr1-xTix)O3 or PZT) ferroelectric ceramics have been widely used in transducers, actuators, and sensors, since they posses high dielectric and piezoelectric properties with a relatively high temperature of operation. Commerciall ...

Origins of electro-mechanical coupling in polycrystalline ferroelectrics during subcoercive electrical loading

Dragan Damjanovic

The electromechanical coupling in ferroelectric materials is controlled by several coexisting structural phenomena which can include piezoelectric lattice strain, 180 degrees and non-180 degrees domain wall motion, and interphase boundary motion. The struc ...
