on 02021-12-19“A "Mott transition" is a metal-nonmetal transition in condensed matter. Due to electric field screening the potential energy becomes much more sharply (exponentially) peaked around the equilibrium position of the atom and electrons become localized and can no longer conduct a current.” A sudden transition, which can be provoked by temperature, pressure, or doping. #physics #band-structure
