WebMar 9, 2024 · Imperfections in Solids: Imperfections in solids refer to deviations from the ideal crystal structure, which can occur due to various reasons during the formation and growth of a crystal.Imperfections in solids can have significant effects on the physical and chemical properties of the material. For example, point defects can affect the electrical … 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 defects typically involve at most a few extra or missing atoms. Larger defects in an ordered structure are usually considered dislocation loops. For historical reasons, man…
WebSep 17, 2024 · Briefly consider the effects of imperfections or crystal defects on a few important properties of solids. The electrical behavior of semiconductors, for example, is largely controlled by crystal imperfections. The conductivity of silicon can thus be altered in type (n or p) and by over eight orders of magnitude through the addition of minute ... WebJun 1, 2012 · Grain boundaries accumulate crystal lattice defects (vacancies, dislocations) and other imperfections, therefore they effect on the metallurgical processes, occurring in alloys and their properties.
