The Barium Strontium Titanate thin film (Ba1-xSrxTiO3) have been deposited on the glass substrate using sol-gel method with variations of composition and annealing temperature assisted with spin coating process at speed 3500 rpm for 30 seconds. The thin film of Ba1-x SrxTiO3 was annealed for 1 hour at temperatures of 600oC, 650oC, and 700oC for each composition variation, namely Ba0,15Sr0,85TiO…
