Nevill Mott

Nevill Mott was an English physicist whose work explained how electron interactions shape the electrical properties of solids, especially transition-metal oxides. He shared the 1977 Nobel Prize in Physics.

Solid-state physics: The study of the physical properties of solids, especially their structure and electronic behavior. This field framed Mott’s investigations of electrons in crystalline materials.
Mott transition: A transition between metallic and insulating behavior driven by changes in electron interactions or bandwidth. Mott analyzed how pressure, composition, or other changes can delocalize electrons.
Rudolf Peierls: A German-British theoretical physicist known for foundational work in quantum theory and solid-state physics. Peierls supervised Mott’s doctoral research and helped shape his early theoretical training.
Nickel oxide: An antiferromagnetic transition-metal oxide that is electrically insulating despite its partially filled electronic bands. Nickel oxide became a classic case for testing Mott’s interaction-based explanation of insulation.
1977 Nobel Prize in Physics: The Nobel Prize awarded to Philip W. Anderson, Nevill Mott, and John H. Van Vleck for theoretical studies of electronic structure in magnetic and disordered systems. The award recognized Mott’s contributions to electronic structure and electron localization in solids.
Band theory: A model of electron energies in solids, in which allowed states form energy bands separated by gaps. Mott examined when band theory succeeds and when electron interactions defeat its predictions.
Mott criterion: A condition estimating when impurity states in a doped semiconductor overlap enough to produce metallic conduction. It quantifies Mott’s account of the insulator-to-metal transition in doped materials.
John H. Van Vleck: An American physicist whose work on magnetic properties of matter earned him the 1977 Nobel Prize in Physics. Van Vleck shared the 1977 prize with Mott and Philip Anderson for theoretical studies of electronic structure.
Vanadium dioxide: A compound that undergoes a sharp transition between insulating and metallic states near room temperature. Its dramatic conductivity change exemplifies the metal–insulator behavior Mott’s work helped explain.
Cavendish Laboratory: The physics laboratory at the University of Cambridge, known for influential research and scientific leadership. Mott directed the Cavendish Laboratory from 1954 to 1971, shaping British physics research.
