Composition for forming ferroelectric thin film, method for forming ferroelectric thin film, ferroelectric thin film, and complex electronic component

摘要

A composition for forming a ferroelectric thin film is a composition for forming a ferroelectric thin film consisting of a lead titanate-based perovskite film or a lead zirconate titanate-based complex perovskite film. The composition includes lead acetate, a stabilizing agent consisting of acetylacetone or diethanolamine, and polyvinylpyrrolidone. The ratio of the molar number of the monomer-converted polyvinylpyrrolidone to the molar number of the perovskite B site atoms included in the composition is more than 0 and less than 0.015. The weight-average molecular weight of the polyvinylpyrrolidone is 5,000 to 100,000.
