Abstract

Thin relaxor-ferroelectric Pb_0.9La_0.1(Zr_0.52Ti_0.48)O₃ (PLZT) films were deposited on Si substrates using Ca₂Nb₃O₁₀ (CNOns) and Ti_0.87O₂ (TiOns) nanosheets as the growth template layer and SrRuO₃ (SRO) as the base electrode layer, using pulsed laser deposition. XRD and cross-sectional SEM results show that the structure of the PLZT layers changes from very dense with (001)-orientation to columnar with (110)-orientation for CNOns and TiOns, respectively. The recoverable energy-storage density (U_reco) is nearly proportional to the critical electric breakdown field (E_BD), which increases with PLZT film thickness. A very high U_reco value of 58.4 J cm^-3 and energy-storage efficiency (η) of 81.2% were obtained at an E_BD of 3400 kV cm^-1 for the 1000 nm thick PLZT film on CNOns/Si, significantly higher than for the film on TiOns/Si (U_reco = 44.0 J cm^-3 and η = 59.6% for E_BD = 2800 kV cm^-1). This excellent energy storage performance in the PLZT/SRO/CNOns/Si is due to the dense film structure and nearly hysteresis-free relaxor behavior. These results are important for improving the performance of relaxor-ferroelectric thin films for high-power capacitor applications.
