SrLaAlO4 crystal is a promising substrate material for high Tc superconducting film and other oxide films to replace SrTiO3 crystal with better quality and lower cost. MTI produces SrLaAlO4 crystal and substrate in the house up to 35 mm. We strongly recommend to customers to use SrLaAlO4 substrate instead of SrTiO3, if possible, to improve epitaxy film quality. Please see the resources below for a comparison of SrTiO3 - LaAlO3 - SrAlO4 Crystal.
