Enhanced electro-mechanical coupling of TiN/Ce0.8Gd0.2O1.9 thin film electrostrictor
Abstract
Gadolium doped ceria, Gd:CeO<sub>2</sub> (CGO), have recently been shown to possess an exceptional high electrostriction coefficient (<i>Q</i>), which is at the least three orders of magnitude larger than the best performing lead-based electrostrictors, e.g. Pb(Mn<sub>1/3</sub>Nb<sub>2/3</sub>)O<sub>3</sub>.Herein, we show that CGO thin films fabricated by a pulsed laserdeposition method can be directly integrated onto the Si substrate byusing TiN films of few nanometers as functional electrodes. Theexceptional good coupling between TiN and Ce<sub>0.8</sub>Gd<sub>0.2</sub>O<sub>1.9</sub> yields a high electrostriction coefficient of <i>Q</i><sub>e</sub> = 40 m<sup>4</sup> C<sup>−2</sup> and a superior electrochemomechanical stability with respect to the metal electrodes.
