Application:
SrTiO3 is also the preferred single crystal material for high temperature superconducting junction technology
(using bimorph or stepped substrates) and substrate stepping (beveling and heat treatment at specific angles).
Barium titanate (SrTiO3) is one of the most widely used high-temperature superconducting single crystal substrates. It has good lattice matching with high temperature superconducting materials such as YBaCuO, has no twin structure, and has excellent physical and mechanical properties. A variety of high-temperature superconducting thin films (Y-series, Bi-series, La-series, etc.) fabricated using various film forming techniques (such as magnetron sputtering, pulsed laser deposition, laser molecular beam epitaxy, etc.) can obtain TCO ≥ 90°K, JCO≥106A/cm2 and other indicators. SrTiO3 is also the preferred single crystal material for high temperature superconducting junction technology (using bimorph or stepped substrates) and substrate stepping (beveling and heat treatment at specific angles).
