    Abstract

    Barium Strontium Titanate (BST) and Lanthanum doping BST (BSLT) thin films have been successfully grown by sol gel method on the substrate Pt / Si which were prepared with spin coater. Thin layer of BST and BSLT made of 3 layers with mole ratio of Barium (Ba) and Strontium (Sr) 0.8:0.2 and mole prosentage variation of composition Lanthanum (La) as dopant 1%, 3% and 5%. The thin film samples of BST and BSLT were characterized by XRD (X-ray Diffraction) and do refinement process by GSAS software.XRD characterization showsthat along with the increase in mole prosentage of composition Lanthanum (La) as dopant ,the difraction angle shifts to the left (smaller). Lattice parameter values from refinement process showsthat a thin layer of BST and BSLT have a tetragonal structure. Keyword :BST, BSLT, sol gel, spin coater, lattice parameter
