The rapid development of technology and science, especially in the field of electronics, has made ferroelectric materials a material that attracts a lot of attention. One of the growth of thin layers is the sol-gel method. A thin layer of (0,5)BaTiO3 - (0,5)Ba(Zr0.5Ti0.5)O3) has been made using the sol-gel method on an FTO substrate prepared by spin coating process. A thin layer of (0,5)BaTiO3 …
