LaSrAlO4

Breif intruduction of SrLaAlO4 single crystal substrate

SrLaAlO4 single crystal substrate  has no luan crystal and phase transition from the melting point to low temperature.

It has the same structure with high temperature superconductor YBCO.

Thermal expansion coefficient is lower than other perovskite structure crystals.

Can deposition film to improve lattice mismatch and reduce stress.
