IMPROVEMENTS TO OXIDE FILMS

摘要

An oxide film having improved fatigue-switching characteristics suitable for use in non-volatile electronic memories has the composition: - (Pb1+delta(Zr1-XtiX)1-Z MnZ03) (where 0.06 Ü x Ü 1, 0 < z < 0.2, 0 Üdelta< 0.2) The film is produced using a solution of manganese doped lead zirconate titanate obtained by dissolving precursors in a hybrid solvent including methanol, ethanol and acetic acid without removing water during synthesis. The resulting solution is resistant to hydrolysis and may be deposited on a substrate by spin or dip coating, dried and fired to develop an oxide film having a perovskite microcrystalline structure.
