Ba(Zn1/3Nb2/3)O3 thin films obtained by polymeric precursors method

In this work Ba(Zn1/3Nb2/3)O3_3$ thin films were prepared by the polymeric precursors method. A detailed description of the procedure to obtain the precursors and deposition was presented. High quality polycrystalline films of Ba(Zn1/3Nb2/3)O3 were obtained from Pt/Ti/SiO${}_2$/Si substrate deposited by spin coating technique. X ray measurements show that the film crystallizes in a partial ordered trigonal structure characteristic of the 1:2 complex perovskites. The partial order and structure was confirmed by Raman measurements. Also, confocal Raman and atomic force microscopy was used to characterize the film morphology.
