Strontium titanate (SrTiO₃) is a ceramic perovskite compound that exhibits semiconductor properties and is valued for its high dielectric constant, structural stability, and optical transparency. It is widely used in multilayer capacitors, tunable microwave devices, and photocatalytic applications, where its ability to be engineered with dopants and defects makes it attractive for energy conversion and environmental remediation. The material is also extensively studied in thin-film form for oxide electronics, ferroelectric devices, and as a substrate for growing complex oxide heterostructures—making it a bridge between classical ceramics engineering and next-generation functional materials research.
