Abstract
In solutionprocesses the formation of multistacked layers MSLs is difficult because of natural dissolution and/or damage to the underlying film by the solvent used for the upper film To form MSLs in solutionprocesses using orthogonal solvents for each layer is a representative remedy As the number of MSLs increases the selection of appropriate solvents for every layer becomes harder In this work we report a viable method to form MSLs even when using one material for the entire solutionprocess We present that solutionprocessed MSLs can be formed by tuning the solubility by mixing an orthogonal solvent We fabricated ferroelectric MSLs using a ferroelectric polymer and applied the MSLs into a ferroelectricgated fieldeffect transistor We obtained improvements in electrical properties such as current on/off ratio subthreshold swing and mobility in transistors with MSLs in comparison to the single layer case
