Growth SectorとOrderingのOptics

抄録

Ordering of two kinds of atoms will occur on a side face of growth step due to the charge balance and the difference in ionic radii. When a crystal grows in a solution with low supersaturation, a three-dimensional lattice is produced by the stacking of two-dimensional lattices. The two-dimensional atomic arrangements exposed on the side planes of the growth steps and their symmetry affect the degree of ordering produced during growth, that is, order-disorder structure is determined by the direction of growth step. Optical method is useful to detect a very small variation of the ordering.
