Strontium titanate (SrTiO3)

SrTiO3 is an insulating material that can be transformed into ferroelectric materials or superconductors through chemical doping, pressure, strain, or isotope substitution.single-crystal It is one of the most widely used excellent High-temperature superconductivity single crystal substrates. It has good lattice matching with High-temperature superconductivity materials such as YBa2Cu3O7, no twin structure, and excellent physical and mechanical properties. TCO 90 ° K, JCO 106A/cm2 can be obtained from various High-temperaturesingle-crystal superconductivity films (Y line, double line, La line, etc.) prepared by various film preparation technologies (such as magnetron sputtering, Pulsed laser deposition, laser Molecular-beam epitaxy, etc.). SrTiO3 is also the preferred single crystal material for High-temperature superconductivity junction technology (using double crystal substrate or step substrate) and substrate step (oblique cutting at a specific angle).
SrTiO3 is an insulating material that can be transformed into ferroelectric materials or superconductors through chemical doping, pressure, strain, or isotope substitution.
Strontium titanate is one of the important perovskite solar cell materials, and perovskite is a kind of material with good photoelectric properties. Therefore, the growth of perovskite on Strontium titanate is a hot research topic in recent years.
