SPRAY PYROLYSIS APPROACH FOR PREPARING MgO THIN FILMS
-
Abstract
oriented MgO thin films have been successfully prepared on Si substrate by a simple spray pyrolysis method started from magnesium acetate. The results indicated that substrate temperature and deposition rate are key factors to grow MgO films and (100)-oriented MgO films which were obtained when the substrate temperature and the flow rate of O2 was 6000C and 2.5L/min, respectively. In addition, the microstructure of the MgO thin films were examined with X-ray diffraction (XRD), transmission electron microscopy (TEM) and atomic force microscopy (AFM).
