Al the same time, the dielectric constant of the BZ. I film also increases as the annealing temperature increases. In particular, the optimal energy-storage density of 30.9 J/cnr and a large energy-storage efficiency of 67.8% could be obtained in the film annealed at 500 which not only achi Effect of zr and la based co doping on electrical properties of lead free barium titanate batio3 thin films eved a large breakdown strength (up to 7000 kV/cm) but also exhibited a great temperature-dependent energy storage performance stability in a wide temEffect of zr and la based co doping on electrical properties of lead free barium titanate batio3 thin films
