Imperfections in crystals
WitrynaImperfections in Solids Generally, an idealized solid (perfect order exists throughout crystalline material) i.e., real perfect crystal does not exist; all contain large numbers of various defects or imperfections. Many of the important properties of materials are due to the presence of these imperfections. WitrynaA planar defect is a discontinuity of the perfect crystal structure across a plane. Interfacial defects are boundaries that have two dimensions and normally separate …
