Variations in the regular arrangement of atoms in crystals affecting their properties.
Summary
Defects in crystal lattices are crucial for understanding the properties and behaviors of materials. They can be classified into point defects, line defects, and surface defects, each affecting the material's characteristics in unique ways. For instance, point defects like vacancies can enhance diffusion, while dislocations allow for plastic deformation, making materials more ductile. Understanding these defects is essential for various applications, including semiconductor technology and materials engineering. By manipulating defects, scientists and engineers can tailor materials for specific uses, improving performance in electronics, construction, and nanotechnology. This knowledge is foundational for advancing material science and engineering practices.
