Final answer:
To calculate the temperature at which the position of the energy level is 3kT above the Fermi energy (EF), you can use the equation kB T = E - EF, where kB is the Boltzmann constant.
Step-by-step explanation:
To calculate the temperature at which the position of the energy level is 3kT above the Fermi energy (EF), we can use the equation kB T = E - EF, where kB is the Boltzmann constant.
Since the energy difference is 3kT, we can rewrite the equation as 3kT = E - EF and solve for T. Rearranging the equation gives T = (E - EF) / (3kB).
Substituting the given values for E, EF, and k, we can calculate the temperature.
