how to estimate the fermi temperature using any value of m* Solution All the particles are at the same temperature, regardless of their energy. Temperature is a property of a distribution of energies of particles not a single particle . The Fermi Dirac distribution notice that relation Ef/Kb. The right units to be called temperature. It turns out the system behave more and more differently beyond that temperature. Fermions may be at the same temperature is purely quantum mechanics. Fermi temperature is that it is just another way expressing the Fermi energy. Ef=kbTf. Which is similar to E=nkbT..
