LSAT - Lanthanum Strontium Aluminum Tantalum Oxide or (La,Sr)(Al,Ta)O3, abbreviated as LSAT, is a crystal with a mixed perovskite structure. LSAT is a hard, transparent oxide composed of the elements lanthanum, aluminum, strontium, and tantalum. LSAT substrates are widely used for epitaxial growth of ferroelectric and high temperature superconductor (HTS) thin films, and in particular popular for epitaxial oxides and their heterostructures, often for the researching purpose of electron correlation phenomena. Typical materials grown on LSAT substrates include strontium titanate (SrTiO3), cuprate superconductors (such as YBCO), iron-based superconductors (iron-pnictides), rare-earth manganites, rare-earth nickelates, and others. Semiconductors such as gallium nitride can also be grown on LSAT.

Hangzhou Shalom EO provides both stocked standard LSAT wafers and custom LSAT wafers.
