WebApr 20, 2000 · If a priori knowledge of the sizes of individual growth faces throughout the crystal's growth history are known, relative growth rates of faces within single crystals can be constrained... WebFeb 2, 2011 · The overall shape of a crystal is defined by the rate at which the various faces grow; the fastest growing faces disappear, leaving the slowest growing faces to dominate. Lattices can also have a range of defects. These can form sites for rapid crystal growth and, in some cases, are the dominant means for crystal growth.
