摘要

The influence of substrate temperature on structural and dielectric properties of cubic pyrochlore Bi _1.5 Zn _1.0 Nb _1.5 O ₇ (BZN) thin films prepared by pulsed laser deposition process has been investigated. BZN thin films were deposited on Pt/Ti/SiO ₂ /Si(1 0 0) substrate and in situ annealed at 700 °C. The results indicate that the substrate temperature has a significant effect on the structural and dielectric properties of BZN thin films. The films exhibit a cubic pyrochlore structure in the substrate temperature range from 550 °C to 700 °C and at the annealing temperature of 700 °C. With further increase of substrate temperature to 750 °C, the phases of Bi ₂ O ₃ , BiNbO ₄ and Bi ₅ Nb ₃ O ₁₅ can be detected in the XRD pattern due to the Zn loss. The dielectric constant and loss tangent of the films deposited at 650 °C are 192 and 6 × 10 ^-4 at 10 kHz, respectively. The tunability is 10% at a dc bias field of 0.9 MV/cm.
