These requirements distinguish twins from polycrystalline aggregates in which the crystallites are randomly oriented. Since the beginning of crystallography as a science, twinned crystals provided objects interes

Growth of Shaped Crystals,The quest to develop such techniques has been driven by the need to minimize costs associated with device fabrication such as cutting or polishing, the loss of expensive materials during these fabrication processes, and the damage created by machining processes.
