Junctions, as physical systems, are localized regions where two or more distinct materials, phases, or structural domains meet and interact, often exhibiting emergent properties not present in the bulk constituents. They can involve interfaces such as metal–semiconductor (Schottky), p–n semiconductor, grain boundaries, or superconducting weak links, and are characterized by spatially varying fields, charge distributions, or order parameters. Junction behavior is governed by boundary conditions, continuity relations, and interfacial energetics, and is central to transport phenomena, including charge, heat, or mass transfer, as well as to device functionality in electronics, photonics, and materials engineering.
