Solid State Physics
Band structure refers to the range of energy levels that electrons can occupy in a solid and is fundamental to understanding the electrical, thermal, and optical properties of materials. This concept is crucial for explaining how symmetry operations affect electron behavior, how reciprocal lattice vectors define allowed states, and how various models such as free electron, tight-binding, and nearly free electron contribute to our understanding of materials. The implications of band structure extend to applications like quantum wells, wires, dots, and advanced materials like carbon nanotubes and graphene.
