Daftar Isi:
- Fabrication of thin film from material barium strontium titanat (Ba0,6Sr 0,4TiO3) that is annealingat a temperature of 6000C and 650°C has been carried out. Samples are made by using the solgelmethod, then characterized by using Field Emission Scanning Microscopy (FESEM) andImpedance Spectroscopy. Results of FESEM for samples at temperature 6000C and 650°C havethickness of 102,7 nm and 245,7 nm. The impedance spectroscopy characterization usesfrequency at 100 Hz up to 1 MHz to get real impedance value and imaginer value fordetermining complex impedance, complex capacitance, dielectric constant. The compleximpedance values for both temperature 600°C and 650°C is 2061,4 Ω dan 4684,3 Ω. Thecomplex capacitance values for both temperature of 6000C and 650°C are 7,72x10-7 Farad and3,4x10-7 Farad. The value of the relative dielectric constant at temperature of 6000C and 650°Care 52,9 and 55,6 respectively.
