The fermi energy level for a particular T = 300K is 6.25 eV. The electrons in this material follow the Fermi-Dirac distribution function.
(a) Find the probability of an energy level at 6.50 eV being occupied by an electron.
(b) Repeat part (a) if the temperature is increased to T = 950K(Assume that Ef is a constant)
(c) Calculate the temperature at which there is a 1 percent probability that a state .30eV below the Fermi level will be empty of an electron.
