Mott Transition

The Mott transition is a phenomenon where a material changes from an insulator to a conductor due to strong interactions between electrons. In certain materials, electrons repel each other strongly enough that they become localized, preventing electrical flow. When conditions like pressure, doping, or temperature change, these interactions weaken, allowing electrons to move freely. This shift from electron localization to mobility causes the material to switch from insulating to conducting without a change in its atomic structure. The Mott transition helps explain how materials can dramatically alter their electrical properties based on electron interactions.
