KTaO3 (Potassium Tantalate) Substrates
KTaO3, or potassium tantalate, is a material that is used as a substrate for various applications in the electronics and optical industries. It has a tetragonal crystal structure and is piezoelectric, meaning it can generate an electrical charge in response to applied mechanical stress. KTaO3 has a high dielectric constant and a large electro-optic coefficient, making it useful for the production of electro-optic modulators and other optical components. Additionally, KTaO3 is often used as a substrate for the growth of other crystal structures, such as lithium niobate and potassium niobate, which are commonly used in optical communication systems. The use of KTaO3 as a substrate can also improve the mechanical stability and surface quality of these structures, making them more suitable for high-precision optical applications.
