Fermi energy of sodium
WebIn the free-electron approximation (3.43), the bare phonon lines of Figs. 3.37 and 3.38 correspond to Fermi temperatures of about 20,000 and 40,000 K, respectively; actual Fermi temperatures are expected to be smaller than these values. We have been discussing the Seebeck effect in the normal state. WebThe Fermi energy also plays an important role in understanding the mystery of why electrons do not contribute significantly to the specific heat of solids at ordinary temperatures, while they are dominant contributors …
