Barium Titanate (BaTiO3) and Strontium Titanat (SrTiO3) are thin layer semiconductors on a ferroelectric crystal that has a perovskite crystal structure so that they can be applied as sensors especially capacitors. The creation of BaTiO3 and SrTiO3 materials in the form of thin films on a glass substrate has been successfully carried out. The method used is the sol-gel method. The goal to be ac…
