What Does FEM Stand For?

FEM stands for Free Electron Model

The Free Electron Model (FEM) is a theoretical framework in solid-state physics that approximates the behavior of conduction electrons in a metal as a gas of free, non-interacting particles. This model simplifies the understanding of electrical conductivity and thermal properties by treating electrons as delocalized over a crystalline lattice, allowing for the derivation of fundamental concepts such as the density of states and the relation between temperature and conductivity. While FEM assumes idealized conditions, it provides foundational insights into the electronic structure of metals and serves as a basis for more complex theories.
