Achieved High Energy Density and Excellent Thermal Stability in (1-x)(Bi0.5Na0.5)0.94Ba0.06TiO3-xBi(Mg0.5Ti0.5)O3 Relaxor Ferroelectric Thin Films
Abstract:In this work, lead-free (1-x)(Bi0.5Na0.5)0.94Ba0.06TiO3-xBi(Mg0.5Ti0.5)O3 (abbreviated as BNBT-xBMT, x = 0.3, 0.4, 0.5 and 0.6) thin films were prepared on Pt/Ti/SiO2/Si substrates using sol-gel method. The microstructures, dielectric and energy storage properties were investigated. The results showed that the addition of BMT disrupted the long-range ferroelectric order and enhanced the relaxor behavior of BNBT-xBMT thin films. In addition, the leakage current density of thin films was also reduced by the dopi… Show more
