LSAT (oxide)

LSAT was originally developed as a substrate for the growth of high Tc cuprate superconductors thin films, mostly of yttrium barium copper oxide (YBCO), for microwave device applications.

[2][3] LSAT's (cubic) lattice parameter of 3.868 Å makes it compatible for the growth of a wide range of perovskite oxides with a relatively low strain.

This property enables the growth of LSAT single crystals using the Czochralski process (CZ), which has commercial advantages.

[5] LSAT's usefulness as a substrate for the growth of such films stems from its high chemical and thermal stability, and very low electrical conductivity.

LSAT on the other hand, is stable in both oxidizing and fairly reducing environments in high temperatures, thus enabling a larger window for the processing and growth conditions.
