It is named after Walter Schottky, who first described it in 1911.<\/p>\n<p>A Schottky defect is a dislocation in a crystal lattice that is caused by the intersection of a plane of atoms with a surface. It is a type of edge dislocation. The plane of atoms that intersects the surface is known as the Schottky plane. The dislocation line that runs along the edge of the Schottky plane is known as the Schottky line.<\/p>\n<p>Schottky defects are usually caused by the intersection of a plane of atoms with a surface. However, they can also be caused by the intersection of a plane of atoms with a grain boundary. Schottky defects can cause a variety of problems in a crystal lattice, including decreased strength, decreased toughness, and decreased electrical and thermal conductivity.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Characteristics_of_Schottky_Defects\"><\/span>Characteristics of Schottky Defects<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Schottky defects are created when an electron jumps from a valence band to a conduction band, leaving behind a &#8220;hole&#8221; in the valence band. These defects can cause a number of problems in semiconductor devices, including increased leakage current and decreased carrier mobility.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Concentration_of_Defects\"><\/span>Concentration of Defects<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Concentration of defects is the number of defects present in a unit area or volume of material. The concentration of defects can be measured in terms of the number of defects per unit area or volume of material. The concentration of defects affects the performance and lifetime of a device.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Schottky_Defect_and_Frenkel_Defect\"><\/span>Schottky Defect and Frenkel Defect<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Schottky_defect\"><\/span>Schottky defect:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A Schottky defect is a type of point defect in a crystal lattice. It is named after Walter H. Schottky, who first described it in 1914.<\/p>\n<p>A Schottky defect is created when a metal atom occupies a site in the crystal lattice of an ionic solid. When the metal atom replaces a cation, a Schottky defect is created. When the metal atom replaces an anion, a Frenkel defect is created.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Frenkel_defect\"><\/span>Frenkel defect:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A Frenkel defect is a type of point defect in a crystal lattice. It is named after Boris Frenkel, who first described it in 1926.<\/p>\n<p>A Frenkel defect is created when a non-metal atom occupies a site in the crystal lattice of an ionic solid. When the non-metal atom replaces a cation, a Frenkel defect is created. When the non-metal atom replaces an anion, a Schottky defect is created.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Bound_and_Dilute_Defects\"><\/span>Bound and Dilute Defects<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The concentration of defects in a material can be controlled by thermal treatment, alloying, and other methods. When a material is heated above its solubility limit, the defects become more mobile and the concentration of defects increases. The concentration of defects can also be controlled by alloying. In alloys, the solubility of defects is reduced, and the concentration of defects is reduced.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Definition of Schottky Defect A Schottky defect is a type of defect that occurs in a crystal structure.
