edge dislocation
Quick Summary
An edge dislocation is a type of crystal defect in crystallography. It occurs when an extra half-plane of atoms is inserted into an otherwise perfect crystal lattice, creating a line defect. This imperfection disrupts the regular arrangement of atoms along a line, causing strain in the surrounding crystal structure. Edge dislocations are formed during crystal growth and can influence a material's mechanical properties, often making it harder. They are a fundamental concept in understanding the behavior of crystalline solids.12
