Crystallographic defect wikipedia
WebSchottky defect. A Schottky defect is an excitation of the site occupations in a crystal lattice leading to point defects named after Walter H. Schottky. In ionic crystals, this defect forms when oppositely charged ions leave their lattice sites and become incorporated for instance at the surface, creating oppositely charged vacancies. WebA 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 …

WebA crystal oscillator is an electronic oscillator circuit that uses a piezoelectric crystal as a frequency-selective element. The oscillator frequency is often used to keep track of time, as in quartz wristwatches, … WebAnswer (1 of 2): I like Jozef's answer, but to add: You can't do much *retrospectively* to reduce defects in a crystal; that crystal's a solid, duh. You can maybe do Zone melting - Wikipedia (as Jozef implies), but that only works for silicon because it's an element, and won't decompose if you ...
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 defects are interruptions of regular patterns in crystalline solids. They are common because positions of atoms or molecules at repeating fixed distances …
WebIn crystallography, a vacancy is a type of point defect in a crystal where an atom is missing from one of the lattice sites.[2] Crystals inherently possess imperfections, sometimes referred to as cystallographic defects.
