摘要
以醋酸铅和异丙醇锆为原料,乙二醇甲醚为溶剂。通过溶胶-凝胶法和快速退火工艺在Pt(111)/Ti/SiO2/Si(100)基片成功地制备出不开裂的钙钛矿PbZrO3薄膜。用XRD和原子力显微镜测量了薄膜随退火温度变化的结构和表面形貌特征,用XPS测试了650°C退火PbZrO3薄膜的表面化学态。
PbZrO3 thin films on Pt(111)/Ti/SiO2/Si(100) substrates were prepared by a SolGel process and rapid thermal annealing (RTA).Using analytically pure lead acetate hydrate Pb(CH3COO)2·3H2O,and zirconiumnproponed Zr(O(CH2)2CH3)4 as starting materials;2methoxyethanol C3H8O2 as a solvent.PbZrO3 films grown on Pt/Ti/SiO2/Si substrates annealed at various temperatures from 450 °C to 650 °C for 10 min,the structure,surface morphology and chemical states have been measured by XRD,AFM and XPS.
