16 results about "Vacancy defect" patented technology

In crystallography, a vacancy is a type of point defect in a crystal. Crystals inherently possess imperfections, sometimes referred to as crystalline defects. A defect in which an atom is missing from one of the lattice sites is known as a "vacancy" defect. It is also known as a Schottky defect, although in ionic crystals the concepts are not identical. Vacancies occur naturally in all crystalline materials.
