defektabsorption

Defektabsorption refers to the process by which defects within a material are incorporated or assimilated into a larger structure or matrix. This phenomenon is particularly relevant in materials science and engineering, where the presence and behavior of defects can significantly influence a material's properties. Defects can range from point defects like vacancies and interstitials to line defects such as dislocations, and even planar defects like grain boundaries. The absorption of these defects can occur during material processing, such as heat treatment or deposition, or through the material's interaction with its environment. For example, in the context of semiconductor manufacturing, impurities or lattice imperfections can be absorbed during crystal growth, affecting the electrical characteristics of the resulting material. Similarly, in metallic alloys, dislocations can be absorbed at grain boundaries, influencing the material's strength and ductility. Understanding defektabsorption is crucial for controlling material performance, as the concentration and distribution of absorbed defects can lead to changes in mechanical strength, electrical conductivity, optical properties, and chemical reactivity. Techniques like transmission electron microscopy (TEM) and X-ray diffraction (XRD) are often employed to study and characterize the presence and impact of absorbed defects within materials. The study of defektabsorption helps in designing materials with tailored properties by managing the internal defect structure.
