Controlling Piezoelectric Responses in Pb(Zr_0.52Ti_0.48)O₃ Films through Deposition Conditions and Nanosheet Buffer Layers on Glass.

ABSTRACT: Nanosheet Ca₂Nb₃O₁₀ (CNOns) layers were deposited on ultralow expansion glass substrates by the Langmuir-Blodgett method to obtain preferential (001)-oriented growth of Pb(Zr_0.52Ti_0.48)O₃ (PZT) thin films using pulsed laser deposition (PLD) to enhance the ferroelectric and piezoelectric properties of the films. The PLD deposition temperature and repetition frequency used for the deposition of the PZT films were found to play a key role in the precise control of the microstructure and therefore of the ferroelectric and piezoelectric properties. A film deposited at a high repetition frequency has a columnar grain structure, which helps to increase the longitudinal piezoelectric coefficient (d_33f). An enhanced d
