KARAKTERISASI KAPASITOR BARIUM STRONTIUM TITANAT (BST) Ba0,75 Sr0,25 TiO3 , YANG DIBUAT MENGGUNAKAN METODE SOL-GEL

Abstract

The thin film of Barium Strontium Titanate (BST) has been studied withcomposition ofby using sol-gel method that annealed in temperature of 600^oC and 650^oC. The thin film of BST is characterized by using Field Emission Scanning Electron Microscopy (FESEM) and an impedance spectroscopy. The results of  FESEM characterization for samples in temperature of 600^oC and 650^oC are 55.83 nm and 84.88 nm in thickness respectively. The result of impedance spectroscopy characterization given frequency values obtained by the impedance value of real and imaginary.The capacitance value at a frequency of 20 Hz from a thin film of BST in temperature of 600^oC and 650^oC are 69.36Fand138.70F. The dielectric constant of the thin film of BST in temperature of 600^oC and 650^oC are 22.17 dan 131.56 respectively.
