Number Density Of Free Electrons. ... The temperature of the electron gas is the same as the temperature of the metal,. The number density of free electrons (the number of free electrons per unit volume, n) depends on the choice of metal.
Number Density Of Free Electrons
Free electrons in a metal are assumed to collide occasionally with the lattice ions, but otherwise the details of the interactions between electrons and ions are neglected, as is the Coulomb repulsion between electrons. Left undisturbed, the electron gas settles down to a state of thermal equilibrium, characterized by a particular temperature and number density. The temperature of the electron gas is the same as the temperature of the metal,. The number density of free electrons (the number of free electrons per unit volume, n) depends on the choice of metal.
