Abstract

The predominant cleavage plane in LiNbO₃ is known to be of the general (01.2) type.¹ However, neither the absolute orientation of the plane with respect to the standard crystal x, y, z axes nor with respect to the lattice structure has been determined. Recent interest in the use of x-cut plates with cleaved end-faces for use in electrooptic devices^2-4 has prompted us to establish the absolute orientation of the cleavage plane.
