Daftar Isi:
- A thin film of material Barium Strontium Titanate (BST) with compositions of Ba0.3Sr0.7TiO3made using sol-gel method and annealing at temperatures 600°C and 650°C to obtaincrystalline structure. The thin film of BST was characterized by using Field EmissionScanning Electron Microscopy (FESEM) and impedance spectroscopy. The resultsofcharacterization using FESEM obtained the thickness of thin film Ba0.3Sr0.7TiO3at atemperature 600oC and650oC are 69.22 nm dan 73.69 nm. The value mass composition ofBa:Sr:Ti obtained from the characterization EDX at temperatures 600°C is 0.3:1.7:3.8 and attemperatures 650oCis 0.1:0.3:0.8. The result of impedance spectroscopy obtained afrequency, real impedance (Z’) and imaginer impedance (Z”). The result of impedance alsoobtained information that the greater frequency, the smaller complex capacitance anddielectric constant and vice versa. In general the greater annealing temperature, complexcapacitance and the dielectric constant will be greater too. At the frequence 100 Hz withtemperature 600oCand 650oC, the capacitance value are 1.457x10-5F, 1.476x10-5 F. At thefrequence 100 Hz with temperature 600oCand 650oC, the dielectric constant value are 670dan 723.
