Witryna15 maj 2024 · Crystals are physical arrays delineated by polar surfaces and often contain imperfections of a polar nature. Understanding the structure of such defects on the molecular level is of topical importance since they strongly affect the macroscopic properties of materials. Witryna1 wrz 2015 · A real crystal always has a large number of imperfections in the lattice. Since real crystals are of finite size, they have a surface to their boundary. At the boundary, atomic bonds terminate and hence the surface itself is an imperfection. One can reduce crystal defects considerably, but can never eliminate them entirely. PH …

A crystallographic defect is an interruption of the regular patterns of arrangement of atoms or molecules in crystalline solids. The positions and orientations of particles, which are repeating at fixed distances determined by the unit cell parameters in crystals, exhibit a periodic crystal structure, but this is usually imperfect. Several types of defects are often characterized: point defe…
