Strontium Titanate (SrTiO3) is a material that has been widely used as a substrate in various fields, such as electronics, optics, and energy technology. It is known for its high dielectric constant and low loss tangent, making it a suitable substrate for capacitors and microwave devices. SrTiO3 is also a good insulator and can withstand high temperatures, making it a suitable substrate for high-temperature applications. In addition, SrTiO3 has a large bandgap and a high electron mobility, making it a good candidate for use as a substrate in optoelectronic devices such as LEDs, solar cells, and photodetectors. The SrTiO3 substrate can be manufactured by a number of different methods, including the traditional ceramic synthesis method and the more modern solution-based and thin film growth methods.
