Effect of Annealing Temperature on the Microstructure of Barium Strontium Titanate Films
Barium strontium titanate (Ba1-xSrxTiO3,BST) films have been prepared on Pt/Ti/SiO2/Si by medium frequency (MF) magnetron sputtering,and subsequently in situ crystallized at 500-700℃.The microstructures of the MF-BST films are studied.BST films prepared by radio frequency (RF) magnetron sputtering and exhibited preferential (110) orientation,are compared.XRD shows that the MF-BST films exhibit preferential (111) orientation and better crystallization than the RF-BST films at the same annealing temperature.AFM displayed that the MF-BST films were smooth and compact.XPS analysis exhibited that the MF-BST films revealed better surface and interface structural characteristics.Their dielectric properties were also compared.
