Crystal growth adds atoms, ions or molecules to an ordered crystal structure from a melt, solution or vapor. Growth competes with nucleation: a seed can favor one growing crystal, whereas many independent nuclei can produce a polycrystalline solid. Temperature and concentration gradients control transport to the interface, while interfacial attachment determines how arriving species join the lattice. A flat interface is not guaranteed; instabilities can create cellular or dendritic shapes. Epitaxy is the special case where a substrate guides the orientation of the growing crystalline layer.
Crystal growth is the process through which a solid crystalline structure forms from a solution, melt, or vapor. This process is significant in various fields, including materials science, chemistry, geology, and biology, as it affects the properties and behaviors of materials. **Key aspects of crystal growth include:** 1. **Nucleation:** This is the initial stage where small clusters of molecules or atoms come together to form a stable nucleus.
