In the below diagram, the electrons (black dots) can fill the energy levels (boxes) with different configurations (each row is a different configuration) of the same overall energy. The columns are the different energy levels, separated by an equal amount of energy. In units of energy, estimate the Fermi Energy and the temperature (in units of the Fermi energy divided by the Boltzmann constant)? Solution Fermi energy=Highest energy-lowest energy=17-0=17 units Given that Temperature=fermi energy/Boltz mann constant=17/1.38*10^-23=12.319*10^23.
