Improved Thin Film
Background Thin film deposition of metal oxide materials from aqueous solution is challenged by the solubility and gelling behavior of precursors. For example, some metal cations are poorly soluble at neutral pH, but added acid or base is detrimental to substrate stability and film adherence. In addition, soluble salts of metal cations tend to crystallize...
