Crystalline LaAlO3 has a relatively high relative dielectric constant of ~25. LAO's crystal structure is a rhombohedral distorted perrovskite 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.
