Converse mode piezoelectric coefficient for lead zirconate titanate thin film with interdigitated electrode

Paul Muralt, Ramin Matloub Aghdam, Robin Nigon, Silviu Cosmin Sandu, Andrea Mazzalai, Nachiappan Chidambaram, Davide Balma

The use of interdigitated electrodes (IDEs) in conjunction with ferroelectric thin films shows many attractive features for piezoelectric MEMS applications. In this work, growth of {1 0 0}-textured lead zirconate titanate (PZT) thin films was achieved on i ...

High Piezoelectric Longitudinal Coefficients in Sol-gel PZT Thin Film Multilayers

Paul Muralt, Andrea Mazzalai, Antonia Neels, Silviu Cosmin Sandu, Nachiappan Chidambaram, Alex Dommann, Davide Balma

A five-layer stack of lead zirconate titanate (PZT) thin films with Pt electrodes was fabricated for potential applications in nanoactuator systems. The 1 mu m thick PZT films were deposited by a sol-gel technique, the platinum electrodes by sputtering. Th ...

Characterization and Fatigue of the Converse Piezoelectric Effect in PZT Films for MEMS Applications

Paul Muralt, Ramin Matloub Aghdam, Andrea Mazzalai, Nachiappan Chidambaram, Davide Balma

A measurement setup for the detailed study of the transverse piezoelectric coefficient e(31,f) in the converse (actuator) mode was developed. It allows the assessment of the piezoelectric stress in thin films on silicon cantilevers and provides for a corre ...
