Question 2:
The Fermi energy level for a particular material at T = 300 K is 5.50 eV. The electrons in this
material follow the Fermi-Dirac distribution function.
a) Find the probability of an energy level at 5.50 eV being occupied by an electron.
b) Repeat part (a) if the temperature is increased to T = 600 K. (Assume that
EF is a constant.).
c) Calculate the energy level where probability of finding an electron at room temperature is 70%.
d) Calculate the temperature at which there is a 7 percent probability that a state 0.4 eV below the Fermi level will be empty of an electron.
