The Nearly Free Electron Model (NFEM) is a theoretical framework used in solid-state physics to describe the electronic properties of metals and some semiconductors. This model extends the free electron model, which treats electrons in a solid as if they were free particles moving in three-dimensional space without any potential energy influence from the atomic lattice of the solid.
