Impurity defects in solids
WitrynaAn impurity defect is a crystal lattice distortion caused by an impurity (foreign atom/ion) occupying an interstitial site in the lattice or replacing the parent atom/ion in the regular sites. Impurity defects can be classified into the following type is: Substitutional impurity Interstitial impurity Substitutional Impurity Witryna2 lis 2014 · Imperfections in Solids Linear Defects (Dislocations) • Are one-dimensional defects around which atoms are misaligned • Edge dislocation: • extra half-plane of atoms inserted in a crystal structure • b to dislocation line • Screw dislocation: • spiral planar ramp resulting from shear deformation • b to dislocation line Burger’s vector, b: …
