Thin film substrate

    The strontium lanthanum aluminate crystal has no twinning and phase transition from the melting point to the low temperature. It has the same structure as the high-temperature superconductor YBCO. Compared with other substrates, the <001> plane has a moderate lattice mismatch with YBCO<001>. (2.5~3.5%). At the same time, the thermal expansion coefficient of this crystal is lower than that of other perovskite crystals, which can deposit films at lower temperatures to improve lattice mismatch and reduce stress.
