Abstract

Barium zirconate titanate (BaZr0.2Ti0.8O3, BZT) 250nm thick thin films were fabricated by pulsed laser deposition and the influence of the substrate temperature on their preferred orientation, microstructure, morphology and dielectric properties was investigated. Dielectric measurements indicated the (1 1 0)-oriented BZT thin films deposited at 750°C to show good dielectric properties with high dielectric constant (~500 at 100kHz), low loss tangent (<0.01 at 100kHz), and superior tunability (>70% at 400kV/cm), while the largest figure of merit was 78.8. The possible microstructural background responsible for the high dielectric constant and tenability is discussed. In addition, thin films deposited at 750°C with device quality factor of 8738 and dielectric nonlinearity coefficient of 1.66×10−10J/C4m5 were demonstrated.
