Abstract
The effect of Lanthanum (La3+) addition on microstructure, optical and electrical properties of Barium Titanate (BaTiO3) were prepared by using Chemical Solution Deposition (CSD) method. The addition of mole La3+ were 10% and 15% on 0,5 M solubility. Spin coater was used in deposition process of thin films with speed 4000 rpm for 30 seconds. The sandwich-structured Ba1-xLaxTiO3 thin films were grown on a quartz substrate. Thin films were annealed at 850oC with holding time of 1,5 hours. X-Ray Diffraction (XRD) analysis showed the formation of perovskite crystal (ICDD data base PDF
