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).
