Barium Strontium Titanat (BST) thin film is one of the most interesting main materials to study because it posseses a high dielectric constant. This BST thin film can be used for optoelectronic equipment including solar cells, photosensors and color sensors. Compositions of thin films Barium Strontium Titanat (Ba1-xSrxTiO3) were varied the based on the value of x = 0.25; 0.3; 0.35. These films…
