    Abstract: A Zr-doped (Ba,Sr)TiO3 perovskite crystal material dielectric thin film. Such dielectric thin film is characterized by at least one of the characteristics including: (a) a breakdown strength of at least 1.3 MV/cm; (b) a leakage current of not more than 1x10 A/cm under applied voltage of about +/-3V or above and at temperature of about 100 DEG C or above; and (c) an energy storage density of at least 15 J/cc. The dielectric thin film comprises zirconium dopant in the amount of 0.5% to 50% by total weight of the Zr-doped (Ba,Sr)TiO3 perovskite crystal material, preferably 2-15%, more preferably 4% to 14%, and most preferably 5% to 12%. Such dielectric thin film in a preferred aspect is deposited by a MOCVD process using metal precursors Ba(thd)2-polyamine, Sr(thd)2-polyamine, Zr(thd)4, and Ti(OiPr)2(thd)2 at a deposition temperature inthe range from about 560 DEG C to 700 DEG C.

Such dielectric thin film is characterized by at least one of the characteristics including: (a) a breakdown strength of at least 1.3 MV/cm; (b) a leakage current of not more than 1x10-3 A/cm2 under applied voltage of about ±3V or above and at temperature of about 100° C. or above; and (c) an energy storage density of at least 15 J/cc. The dielectric thin film comprises zirconium dopant in the amount of 0.5% to 50% by total weight of the Zr-doped (Ba,Sr)TiO3 perovskite crystal material, preferably 2-15%, more preferably 4% to 14%, and most preferably 5% to 12%.
