Imperfections in crystals
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.

In fact, using the term “defect” is … 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 …
