metal-insulator transition
1Metal–insulator transition — Metal insulator transitions are transitions from a metal (material with good electrical conductivity of electric charges) to an insulator (material where conductivity of charges is quickly suppressed). These transitions can be achieved by tuning… …
2Metal-insulator transition — Metal insulator transitions refer to changes in the transport properties of a given material. Roughly speaking, materials can be classified as metals, allowing for good conductivity of electric charges, and as insulators, where conductivity of… …
3Mott transition — A Mott transition is a metal nonmetal transition in condensed matter. Due to electric field screening the potential energy becomes much sharper (exponentially) peaked around the equilibrium position of the atom and electrons become localized and… …
4Mott insulator — Mott insulators are a class of materials that should conduct electricity under conventional band theories, but are insulators when measured (particularly at low temperatures). This effect is due to electron electron interactions which are not… …

6Anderson localization — In condensed matter physics, Anderson localization, also known as strong localization, is the absence of diffusion of waves in a disordered medium. This phenomenon is named after the American physicist P. W. Anderson, who was the first one to… …
7Metall-Isolator-Übergang — Als Metall Isolator Übergang bezeichnet man einen Phasenübergang, der auf Quanteneigenschaften der Materie beruht. Dabei treten insbesondere Änderungen der Transporteigenschaften eines Materials, z. B. der elektrischen Leitfähigkeit oder des …
8Mott Criterion — The Mott criterion describes the critical point of the metal insulator transition. The criterion is Where is the electron density of the material and the effective bohr radius. If the criterion is satisfied the material becomes conductive (metal) …
