Abstract:
A method for manufacturing a ferroelectric thin film using a sol-gel process, comprising the steps of:dissolving a Pb precursor using a solvent to prepare a Pb solution and stabilizing a Zr precursor and a Ti precursor to prepare a Zr solution and a Ti solution, respectively; mixing the Zr solution and Ti solution; stirring the Tiâ€”Zr mixed solution with the Pb solution, hydrolyzing the Tiâ€”Zrâ€”Pb solution to prepare a ferroelectric solution; and forming a ferroelectric thin film on a substrate using the ferroelectric solution, wherein the ferroelectric thin film is defined by the general formula Pb(ZrxTi1âˆ’x)O3 where (0
