A Barium Strotium Titanat (BST) capasitor in Ba0,4Sr0,6Tio3 composition using sol-gel method and annealing at temperature 600oC and 650oC to get cristalin has been created. This capasitor characterized using Energy Dispersive X-ray (EDX), Field Emission Scanning Microscopy (FESEM) and impedance spectroscopy instrument. Results of characterization using FESEM obtained thickness of the capasitor …
