Strontium titanate (SrTiO3) is currently the most widely used high-temperature superconducting film of single crystal. Physical, excellent mechanical properties. Use (such as magnetron sputtering, pulsed laser deposition, laser molecular beam epitaxy) produced a variety of high-temperature superconducting thin film (Y-series, Bi-series, La-series) can be obtained TCO ≥ 90 ° K, JCO ≥ 106A / cm2 and other indicators. SrTiO3 is the preferred substrate of single crystal material of a high-temperature superconducting junction technology .
