The transition of unstructured amorphous materials into structured crystalline materials is generally induced by heating materials above their transition temperature. Crystalline materials are important in technology like devices, so alternative ways to control their formation has attracted much interest from materials scientists. Researchers have found that crystallization can be facilitated at a lower temperature than the traditional transition temperature if an amorphous material is agitated at a certain frequency. Thus, agitation represents a possible alternative to temperature for controlling the crystallization of materials.
