Crystro LaAlO3 LAO Substrate Single Crystal For Epitaxial Thin Film

Crystro LaAlO3 LAO Substrate Single Crystal For Epitaxial Thin Film

1. LaAlO3 Crystal property:

Crystalline LaAlO₃ has a relatively high relative dielectric constant of ~25. LAO's crystal structure is a rhombohedral distorted perovskite with a pseudocubic lattice parameter of 3.787 angstroms at room temperature (although one source claims the lattice parameter is 3.82). Polished single crystal LAO surfaces show twin defects visible to the naked eye.
