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 … See more Point defects are defects that occur only at or around a single lattice point. They are not extended in space in any dimension. Strict limits for how small a point defect is are generally not defined explicitly. However, these … See more Line defects can be described by gauge theories. Dislocations are linear defects, around which the atoms of … See more • Three-dimensional macroscopic or bulk defects, such as pores, cracks, or inclusions • Voids — small regions where there are no atoms, and which can be thought of as … See more Density functional theory, classical molecular dynamics and kinetic Monte Carlo simulations are widely used to study the properties of … See more • Grain boundaries occur where the crystallographic direction of the lattice abruptly changes. This usually occurs when two crystals begin growing separately and then meet. • Antiphase boundaries occur in ordered alloys: in this case, the … See more A successful mathematical classification method for physical lattice defects, which works not only with the theory of dislocations and … See more • Bjerrum defect • Crystallographic defects in diamond • Kröger–Vink notation • F-center See more

WebCrystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics ( condensed matter physics ). The word "crystallography" is derived from the Greek word κρύσταλλος ( krystallos) "clear ice, rock ... WebCrystallographic defect. Crystalline solids have a very regular atomic structure: that is, the local positions of atoms with respect to each other are repeated at the atomic scale. … WebCrystallographic defects are interruptions of regular patterns in crystalline solids. They are common because positions of atoms or molecules at repeating fixed distances … puffed a roach
